Starting an Underground Comix collection in 2026 runs through three points of entry: a copy of Zap Comix #1 (Robert Crumb, Apex Novelties, February 1968), regarded as the first modern underground comic and valued at $3,000–$8,000 in CGC 8.0+ second print; the cofounders run of Zap Comix #1–#16 bringing together Crumb, Victor Moscoso, Robert Williams, S. Clay Wilson and Gilbert Shelton; and the essential satellite titles such as Mr. Natural, Fritz the Cat, Keep on Truckin' and The Fabulous Furry Freak Brothers #1 (Gilbert Shelton, Rip Off Press, 1971).
Underground Comix is a precise movement in the history of American comics. Born in San Francisco in February 1968 with the publication of Zap Comix #1 by Robert Crumb, it broke at once with mainstream Marvel/DC comics and with the Comics Code Authority adopted in October 1954. Explicit sex, drugs, political satire, self-deprecation, graphic experimentation: Underground Comix occupied an editorial space that neither EC Comics, nor Mad Magazine, nor the pulps had ever opened up. This guide lays out the historical landmarks (1968–1975), details the 2026 value of the key issue Zap Comix #1, presents the Crumb iconography (Mr. Natural, Fritz the Cat, Keep on Truckin'), maps the catalog of Zap's five cofounders, and gives the collector the priority trade-offs for building a coherent underground collection.
The movement still flies under the radar today compared with Silver Age Marvel or Bronze Age DC. Original print runs are microscopic (1,000 to 5,000 copies for the first prints), high-grade copies are exceedingly rare, and documentation in English remains thin. For a collector starting out in 2026, that is precisely the opportunity: an illiquid market, values rising steadily since 2018, and grails still accessible under $5,000 in CGC 8.0+. The condition is knowing the first-print-versus-reprints distinction, the publishers (Apex Novelties, Print Mint, Rip Off Press, Last Gasp), and the identity of the five Zap cofounders who define the canon.
Underground Comix: the 1968–1975 movement, San Francisco and the counterculture
Underground Comix designates a precise editorial movement, dated and geolocated. Its historical heart sits in San Francisco between February 1968 and 1975, in the wake of the counterculture born from the 1967 Summer of Love (Haight-Ashbury, San Francisco). The spelling "comix" with a final x was codified from Zap Comix #1 onward to mark the break with mainstream comics: the x points both to the X-rated nature of the content and to the graphic experimentation. The term stands explicitly against the Marvel and DC "comic books" subject since October 1954 to the Comics Code Authority, a self-regulatory censorship code imposed after the Kefauver hearings of the U.S. Senate.
The context of 1968 was saturated. The Vietnam War (the Tet escalation in January 1968), the assassination of Martin Luther King on April 4, 1968, the assassination of Robert Kennedy on June 5, 1968, urban race riots, campus protest (Berkeley, Columbia). San Francisco's hippie youth, already familiar with Bill Graham's psychedelic posters (Fillmore Auditorium) and with LSD, was looking for an editorial vehicle to express what neither the press nor mainstream comics dared publish. Robert Crumb, an illustrator born in 1943 in Philadelphia and living in San Francisco since January 1967, drew the pages of Zap Comix #1 during the summer of 1967 in his Haight Street apartment. He printed them at the shop of Charles Plymell, micro-publisher of Apex Novelties, in February 1968. Initial print run: roughly 5,000 copies, sold for 25 cents each by Crumb in person from a baby carriage pushed through Haight-Ashbury.
Underground distribution deliberately refused the traditional comics channels (drugstores, newsstands, the embryonic comic shops). Underground Comix were sold in head shops (stores for marijuana-smoking accessories), alternative record stores (City Lights Bookstore in San Francisco), universities, and by mail order through the classified ads of hippie magazines (Berkeley Barb, San Francisco Oracle, Rolling Stone). This parallel circuit explains the microscopic print runs (1,000 to 10,000 copies for the first titles) and the current scarcity of high-grade copies: most issues were read, handled, lent out, even used as rolling paper.
The Underground Comix movement faded gradually between 1973 and 1975. Three factors converged. First, the Supreme Court's Miller v. California ruling in June 1973, which broadened the legal definition of obscenity to local community standards, exposed publishers to prosecution. Second, the collapse of the head shop market in 1973–1975 under legal pressure (anti-paraphernalia laws). Third, the natural dissolution of the hippie counterculture after the end of the Vietnam War (Paris Peace Accords, January 1973). The movement's spiritual heirs (Art Spiegelman with RAW in 1980, Robert Crumb with Weirdo in 1981, the alt-comix movement of the 1980s–1990s) carried the torch forward, but the historical Underground Comix canon closes firmly in 1975. For placement by ages, see EC Comics Tales from the Crypt: 10 key issues, which details the earlier Pre-Code phase, and investing in modern comics 2020–2026 for the recent dynamic.
Zap Comix #1: February 1968, Apex Novelties, the Crumb first issue
Zap Comix #1, published in February 1968 by Apex Novelties (the short-lived label of Charles Plymell and Don Donahue in San Francisco), is universally regarded as the first modern Underground Comic. Robert Crumb single-handedly produced all 24 pages: cover, scripts, art, inking, lettering. The main title proclaimed "Zap Comix #1 — Mr. Natural in Beware Pussycats! / Fair Warning: For Adult Intellectuals Only!" Standard comic book format (7 × 10.25 in), light pulp paper, black-and-white printing with a full-color cover. Cover price: 25 cents. Documented first-print run: roughly 5,000 copies according to Don Donahue's statements.
The distinction between prints is crucial for the collector. The Apex Novelties first print (February 1968) can be identified by several physical clues: the "Printed by Charles Plymell" line in the colophon, the absence of a printed price on the back cover (sold for 25 cents in cash), and the specific red of the cover printed in slightly uneven ink. The first print is an absolute grail: a CGC 8.5 copy sold at Heritage Auctions in 2021 for around $38,000, a CGC 7.0 between $12,000 and $18,000, and a raw VG/FN remains between $4,000 and $7,000 on the 2026 secondary market.
The second print (May–June 1968, The Print Mint, Berkeley) appeared a few months later, taken over by the publisher The Print Mint after Don Donahue bought back the rights. Identification: the Print Mint line in the colophon, estimated run of 10,000 to 15,000 copies. Its 2026 value is far more accessible: a CGC 8.0+ trades between $3,000 and $8,000 based on Heritage sales for 2024–2025, a CGC 7.0 between $1,500 and $3,000, a raw VG between $600 and $1,200. This is the most rational entry point for a collector who wants to acquire a historic copy without reaching four-figure budgets.
The third, fourth and fifth prints (1969–1974, Print Mint) are, on the other hand, very affordable: between $100 and $400 in raw FN/VF depending on the print, but they hold no investment value and remain reading copies for anyone who wants to discover the content without spending much. The issue's narrative content has itself become historic: "Mr. Natural Visits the City," "Whiteman," "Hey Bo Bo," and the signature one-pager "Keep on Truckin'," which would become the most reproduced (and most counterfeited) image in the Crumb iconography. To understand the value gap between prints and between raw versus slabbed, see CGC comics vintage vs. modern: strategy.
The traceability of a Zap Comix #1 copy is a sensitive subject today: second-print counterfeits and undeclared restored copies are circulating. Before any purchase above $1,000, insist on a CGC or CBCS certificate, and cross-check the provenance via Heritage Auctions or ComicConnect (see ComicConnect vs. Heritage Auctions: comparison). To evaluate a raw copy before slabbing, the free estimate offered by specialized services remains a useful first filter.
Mr. Natural, Fritz the Cat and Keep on Truckin': the Crumb iconography
Between 1965 and 1972, Robert Crumb forged three icon characters that structure the underground imagination and account for a large part of the current value of the comics they appear in. Each has a precise birth certificate, a documented editorial trajectory and a distinct legal status.
Mr. Natural was created in 1967 by Robert Crumb in the satirical magazine Yarrowstalks #2 (Philadelphia, summer 1967). He is a caricatural guru with a long white beard, a yellow robe and bare feet, a blend of the Eastern sage, the wise hobo and the New Age predator. His first appearance in Zap Comix #1 (February 1968) installed the character in the underground canon. Mr. Natural then became the recurring figure of the solo series Mr. Natural published by The San Francisco Comic Book Company and then Apex Novelties: Mr. Natural #1 (1970), #2 (1971), #3 (Cherry Comics, 1977). The #1 first print is valued at $400–$1,200 in CGC 7.0–8.0 in 2026, affordable for anyone wanting to round out a Crumb collection without breaking the bank.
Fritz the Cat is earlier and more legally complex. Robert Crumb drew Fritz, an anthropomorphic student cat and hedonist, as early as his teens (1959–1962) in family fanzines. The first mainstream publication came in 1965 in Harvey Kurtzman's magazine Help! (the founder of Mad), then in Cavalier and R. Crumb's Comics and Stories #1 (1969, Rip Off Press). The character exploded in 1972 with Ralph Bakshi's X-rated animated adaptation Fritz the Cat (the first animated feature film rated X in the United States, released on April 12, 1972, which grossed $90 million on a $700,000 budget). Crumb, unhappy with the result, literally killed off the character in the story "Fritz the Cat, Superstar" published in The People's Comics (1972, Golden Gate Publishing), in which Fritz is stabbed by an ostrich ex-girlfriend. R. Crumb's Comics and Stories #1 (1969) remains a key issue at $300–$800 in CGC 7.0–8.0.
Keep on Truckin' is not a character but a one-page strip published in Zap Comix #1 (February 1968). It depicts four male figures (silhouettes in 1940s suits) walking to the right with an exaggerated stride, disproportionate feet and a swaying gait inspired by the blues musician Blind Boy Fuller ("Keep on Truckin' Mama," 1936). The image became a major cultural meme of the American counterculture between 1968 and 1975: posters, T-shirts, stickers, VW van panels. The legal saga that followed is instructive: Crumb lost his rights to the image in 1977 after suing counterfeiters (the Crumb v. Nelson ruling, which held that Crumb had abandoned his rights by failing to defend the copyright), and partially regained the rights in 1992 after a new lawsuit. Today, owning a Zap Comix #1 means owning the first printing of this founding strip — which contributes significantly to the issue's grail status.
For the collector who wants to build a coherent Crumb core, the 2026 strategy is to target: Zap Comix #1 second print in CGC 7.0+, R. Crumb's Comics and Stories #1 (1969) in CGC 7.0+, Mr. Natural #1 (1970) in CGC 7.0+, and The People's Comics (1972, the death of Fritz) in CGC 7.0+. Estimated total budget: $6,000 to $12,000 for the four issues, to be weighed against the overall strategy described in investing in modern comics 2020–2026.
S. Clay Wilson, Gilbert Shelton, Trina Robbins: the wider catalog
The Underground Comix movement is not limited to Robert Crumb. Three other figures structure the historical canon and offer alternative points of entry to the collector in 2026.
S. Clay Wilson (1941–2021), born Steven Clay Wilson in Lincoln, Nebraska, is the most violent and transgressive author of the movement. His first major contribution is in Zap Comix #2 (June 1968) with the strip "Captain Pissgums and his Pervert Pirates." Wilson drew degenerate pirates, lesbian bikers, knife fights and torture scenes, in a dense ink style saturated with detail. His signature series is The Checkered Demon (Last Gasp, 1977–1998). Wilson's influence on Crumb is documented: Crumb stated in several interviews that reading Wilson's pages in 1968 gave him "permission" to push his own content further. Zap Comix #2 first print Print Mint is valued at $800–$2,500 in CGC 7.0–8.0 in 2026.
Gilbert Shelton (born 1940 in Houston, Texas) is the most commercially successful author of the underground movement thanks to The Fabulous Furry Freak Brothers. Shelton had already been publishing in Austin since 1966 in the magazine The Texas Ranger (University of Texas) before moving to San Francisco in 1968. The Furry Freak Brothers (Phineas, Freewheelin' Franklin, Fat Freddy) made their first appearance in The Rag (May 1968, Austin) and then in Feds 'n' Heads (1968, self-published). The dedicated series The Fabulous Furry Freak Brothers #1 came out in September 1971 from Rip Off Press in San Francisco. The premise: three marijuana-smoking hippies on the run from the police. The slogan "Dope will get you through times of no money better than money will get you through times of no dope" became a generational meme. The Fabulous Furry Freak Brothers #1 first print Rip Off Press is valued in 2026 at $400 to $1,200 in CGC 8.0+, and is arguably the most accessible underground key issue for a collector who wants to enter the canon without reaching Crumb budgets.
Trina Robbins (1938–2024) is the female pioneer of the underground movement. She published in It Ain't Me, Babe Comix #1 in July 1970 (Last Gasp), the first all-female underground comic. The cover, drawn by Robbins, shows Wonder Woman, Olive Oyl, Sheena, Little Lulu and other heroines marching for women's liberation. Robbins then cofounded the collective Wimmen's Comix in 1972 (Last Gasp, the first all-female underground anthology), published for 20 years (1972–1992, 17 issues). It Ain't Me, Babe Comix #1 first print is valued between $600 and $1,800 in CGC 7.0–8.0 in 2026, and represents an investment with strong historical traceability at a time when academic documentation on women in comics is expanding (Robbins herself published A Century of Women Cartoonists in 1993 and From Girls to Grrrlz in 1999, becoming a reference historian).
Other figures round out the underground pantheon and deserve a place in a collection: Spain Rodriguez (creator of the character Trashman, an anarchist activist, Subvert Comics 1970), Bill Griffith (creator of Zippy the Pinhead, Real Pulp Comics 1971, future daily syndicated strip from 1976), Justin Green (author of Binky Brown Meets the Holy Virgin Mary, 1972, the first autobiographical comic in the modern sense, a major influence on Art Spiegelman for Maus), Kim Deitch (creator of Waldo the Cat, The East Village Other 1967–1972), and Victor Moscoso (Fillmore poster artist, cofounder of Zap). For an overall budget framing before entering the grail market, see the most expensive comics 2026.
The five Zap cofounders: Crumb, Moscoso, Williams, Wilson, Shelton
The historical canon of Underground Comix crystallizes around the five cofounders of Zap Comix, the fixed team that drove the series from Zap #2 (June 1968) to the final issue Zap #16 (September 2016, Fantagraphics). This team forms the identifiable heart of the movement, and each cofounder holds a documented place in its history.
Robert Crumb (born 1943) remains the initial architect. He defined the format, signed the majority of the covers, and set the satirical-transgressive tone. Beyond Zap, his solo corpus (R. Crumb's Comics and Stories, Mr. Natural, Hytone Comix, Big Ass Comics, Mr. Snoid, Despair) makes up the bulk of the Crumb tonnage. Crumb emigrated to France in 1991 (Sauve, in the Gard region), where he still lives in 2026. His original art sells for six figures in 2024–2025 at Heritage Auctions (an original drawing for the Fritz the Cat cover reached $717,000 in November 2017).
Victor Moscoso (born 1936 in A Coruña, Spain) was the first to be joined by Crumb. A graduate of Yale (Bachelor of Fine Arts) and the Yale School of Art and Architecture (Master), a student of Josef Albers, Moscoso was above all a major poster artist of the San Francisco psychedelic scene of 1967–1968 (Family Dog, Neon Rose). He joined Zap from Zap #2 (June 1968). His graphic contribution brought formal composition, the use of Letraset, and an Op Art influence (vibrating lines, complementary contrasts). Moscoso is still active in 2026, living in San Francisco.
Robert Williams (born 1943 in Albuquerque, New Mexico) joined Zap from Zap #2 as well (June 1968). A former art director at Ed Roth's studio (Big Daddy Roth Studios, creator of the Rat Fink logo), Williams brought to the movement the kustom kulture, hot rod and lowbrow aesthetic. His Zap pages are saturated with monsters, buxom girls and Roth cars. Williams founded the magazine Juxtapoz Art and Culture in 1994, which became the historical vehicle of the lowbrow art / pop surrealism movement. His painting "Appetite for Destruction" became the original cover of the Guns N' Roses album (1987).
S. Clay Wilson (1941–2021) joined Zap from Zap #2 (June 1968). See the previous section for details. In 2008 he suffered a severe brain injury that left him disabled until his death in 2021. His passing symbolically closes the first underground generation still active.
Gilbert Shelton joined Zap starting with Zap #3 (1969). See the previous section. Shelton emigrated to Paris starting in 1984, where he continued to publish and collaborated with L'Association and then Cornélius. He lives in France in 2026.
Zap's editorial organization is unique: each cofounder gets an equivalent number of pages in each issue, the content is curated collectively, and revenue is shared equally (a cooperative model). This structure explains the title's longevity (1968–2016, that is 48 years for 17 issues, of which 16 are originals plus a Zap #0 printed in 1973 from the lost pages of the first edition). The 2026 value table for the Zap issues shows a clear descending curve: Zap #1 first print ($8,000–$30,000 CGC 8.0+), Zap #2 first print ($800–$2,500), Zap #3 first print ($400–$1,200), Zap #4 first print ($700–$1,800 — censored in 1969 for Crumb's "Joe Blow" strip, ruled obscene by a New York court in March 1973), then Zap #5 through #16 between $80 and $400 each in CGC 8.0+. To structure this catalog in a collection-management tool, the key step is identifying the print, without which the value means nothing. See the dedicated comics app for copy-by-copy management.
2026 values: Zap Comix #1 CGC 8.0+ and Furry Freak Brothers #1
The 2026 pricing of Underground Comix rests on a careful analysis of public sales (Heritage Auctions, ComicConnect, Hake's) over the 2022–2025 period, cross-referenced with the CGC census (the number of copies graded at each level). Below is a detailed read of the two pivots of the market.
For Zap Comix #1 first print Apex Novelties (February 1968), the CGC census in May 2026 lists roughly 145 graded copies across all grades, of which only 7 are in CGC 9.0 or higher. This absolute scarcity justifies the four-figure value. Documented Heritage Auctions sales: a CGC 9.4 sold for $96,000 in November 2022, a CGC 9.0 sold for $38,000 in March 2024, a CGC 8.5 sold for $22,000 in June 2024, a CGC 8.0 sold for $12,500 in September 2024. For the first print, the estimated 2026 value sits at: CGC 9.6 (3 copies recorded) above $100,000, CGC 9.4 between $70,000 and $95,000, CGC 9.0 between $35,000 and $50,000, CGC 8.5 between $18,000 and $28,000, CGC 8.0 between $10,000 and $16,000, CGC 7.0 between $5,000 and $8,500.
For Zap Comix #1 second print Print Mint (May–June 1968), far more accessible, the CGC census lists roughly 420 graded copies. The 2024–2025 sales document: CGC 9.4 between $7,500 and $10,500, CGC 9.0 between $4,500 and $6,800, CGC 8.5 between $3,200 and $5,000, CGC 8.0 between $2,200 and $3,500, CGC 7.0 between $1,100 and $2,000, raw VG between $500 and $900. This second print is what a rational collector targets: a reasonable four-figure entry price, authentic ownership of a historic 1968 copy, and decent resale liquidity on Heritage or ComicConnect.
For The Fabulous Furry Freak Brothers #1 first print Rip Off Press (September 1971), the 2026 value is far less demanding. Initial run estimated at 20,000 copies (higher than the Zaps), CGC census around 380 graded copies. Documented 2024–2025 sales: CGC 9.6 between $3,500 and $5,500, CGC 9.4 between $2,200 and $3,200, CGC 9.0 between $1,200 and $1,800, CGC 8.0 between $450 and $750, CGC 7.0 between $200 and $400, raw VG between $90 and $180. This is probably the best price-to-cult-status ratio on the underground market: for the price of an Amazing Spider-Man #129 CGC 9.0 ($2,200–$2,800 in early 2026), you get a Furry Freak Brothers #1 CGC 9.4 with an equivalent cultural history.
Other underground key issues to know for 2026: Mr. Natural #1 (1970, San Francisco Comic Book Company) CGC 8.0 between $350 and $600; R. Crumb's Comics and Stories #1 (1969, Rip Off Press) CGC 8.0 between $800 and $1,400; Bijou Funnies #1 (1968, Bijou Publishing Empire, Chicago) CGC 8.0 between $400 and $700; It Ain't Me, Babe Comix #1 (1970, Last Gasp) CGC 8.0 between $1,000 and $1,700; Snatch Comics #1 (1968, Apex Novelties) CGC 8.0 between $2,500 and $4,200 — an issue seized by the San Francisco police in March 1968 for obscenity and therefore particularly rare; Young Lust #1 (1970, Print Mint) CGC 8.0 between $200 and $400; Binky Brown Meets the Holy Virgin Mary (1972, Last Gasp) CGC 8.0 between $600 and $1,000.
The value trend over 2018–2026 is positive but less explosive than for Silver Age Marvel: count on an average of 8% to 12% annual appreciation on underground key issues in CGC 8.0+, versus 15% to 25% on some comparable Marvel keys. The reason is structural: a market of specialized collectors, narrow but loyal demand, little short-term speculation. To compare these dynamics with modern sleeper issues, see undervalued comics 2026: sleeper issues. For a complete market overview, also see Mad Magazine: complete collecting guide, which shares the same editorial-niche logic.
FAQ
What exactly defines an Underground Comix?
An Underground Comix meets four cumulative criteria: publication roughly between 1968 and 1975, distribution outside the mainstream comics channel (head shops, alternative bookstores, mail order), content deliberately non-compliant with the Comics Code Authority (sex, drugs, political satire, graphic violence), and the spelling "comix" with a final x adopted as an identity marker. Zap Comix #1 (February 1968, Robert Crumb, Apex Novelties) is regarded as the first modern Underground Comic in the canonical sense of the term.
Why is Zap Comix #1 so expensive in 2026?
Three reasons converge. A microscopic first-print run of about 5,000 copies in February 1968, sold by Robert Crumb in person around Haight-Ashbury. A historic status as the first modern Underground Comic, recognized both by academic criticism (Smithsonian, Library of Congress) and by specialized collectors. A very low CGC census: roughly 145 first-print copies graded in total worldwide in 2026, of which only 7 are in CGC 9.0+. This absolute scarcity drives a four-figure value for the mid grades ($5,000–$8,500 in CGC 7.0) and a five-figure value for the high grades.
How do you tell the first print from the second print of Zap Comix #1?
The February 1968 first print carries the "Printed by Charles Plymell" line in the colophon, the "Apex Novelties" indication as publisher, and no printed price on the back cover (sold for 25 cents in cash). The May–June 1968 second print carries the "The Print Mint, Berkeley" line and a printed price. The red cover has a slightly different tint (more orange on the first print, more bright red on the second). The value difference is massive: a factor of 5 to 8 between the two at an equivalent CGC grade.
What is the best underground key issue to start with on a limited budget?
The Fabulous Furry Freak Brothers #1 first print Rip Off Press (September 1971) in CGC 7.0 between $200 and $400 offers the best price-to-cult-status ratio on the underground market. You get a key issue by Gilbert Shelton, one of the five Zap cofounders, a character emblematic of the counterculture, and a value that has been climbing steadily since 2020. Alternatively, a Mr. Natural #1 (1970) in raw VG around $150–$250 is also a smart entry point for anyone wanting an authentic Robert Crumb signature.
Should you buy slabbed CGC or raw for Underground Comix?
For key issues above $1,000 (Zap #1, Snatch Comics #1, It Ain't Me Babe Comix #1), slabbed CGC or CBCS is necessary: it guarantees authentication, grade, and resale traceability. For issues under $500, raw remains rational provided you buy from a specialized underground dealer (Cherry Comics, Bud Plant, Berkeley) and visually verify the print via the physical clues (colophon, price, print color). Before any raw purchase above $300, systematically cross-check with a free estimate through a recognized service.
