Joker First Appearance: Origin Comic and Key Issue

Spring 1940. Less than a year after his debut in Detective Comics #27, Batman gets his own series. And from the first issue, its creators introduce its ultimate antagonist – the Joker, a criminal clown with a frozen grin, as intelligent as he is sadistic. Batman #1 is an exceptional double key issue: first appearance of the Joker AND first appearance of Catwoman (then named "The Cat"). Two of the most famous villains in world fiction are born in the same issue.

For the collector, Batman #1 is located just behind Action Comics #1 and Detective Comics #27 in the hierarchy of DC Golden Age key issues. The combination of Joker + Catwoman in a single issue, coupled with the extreme rarity of the 1940 comics, makes this one of the strongest investments out there. Prices have regularly reached peaks, driven by the eternal popularity of the Joker in cinema (Nicholson, Ledger, Phoenix).

Publication context

Batman's success in Detective Comics was such that DC offered him a solo title within a few months - an extremely rare occurrence in 1940. Editor Whitney Ellsworth requested a memorable adversary for this first issue. Bill Finger was inspired by the film The Man Who Laughs (1928) with Conrad Veidt – a man with a disfigured smile – to create the Joker. The character was supposed to die in this first issue, but the publisher demanded that he survive, aware of his commercial potential.

The creators

The creation of the Joker is jointly credited to Bob Kane, Bill Finger, and Jerry Robinson—the exact breakdown remains debated. Robinson claims to have contributed the initial concept (a card game joker), Finger the reference to the film The Man Who Laughs, and Kane the graphic synthesis. The drawing of Batman #1 is by Kane with inking by Robinson. The Joker appears already fully formed: white face, green hair, demonic smile, superior criminal intelligence.

The story of the first issue

Batman #1 contains four separate stories. The first and third feature the Joker, who announces his murders on the radio before committing them — a terrifying MO for 1940. He poisons his victims with a poison that freezes their faces into a deadly grin (the "Joker venom"). The second story introduces Catwoman, a jewel thief disguised as an old lady on a yacht. The issue lays the foundation for a universe of adversaries that Batman will face for the next eighty years.

The cover

Bob Kane's cover shows Batman and Robin leaping above the rooftops of Gotham City with the Bat-Signal in the background. Notable fact: neither the Joker nor Catwoman appear on the cover despite their debut on the inside. The purple/midnight blue background and dynamic silhouette of the heroes create an instantly recognizable image that has been praised hundreds of times.

Edition and variants

The circulation of Batman #1 is estimated at between 300,000 and 500,000 copies — a large number for 1940, reflecting the character's already established popularity. There is no variant cover.

The format is quarterly — 64 pages for 10 cents, thicker than standard monthlies. This thickness paradoxically makes conservation more difficult (spine stress, internal pages that pull on the staples). The quality of the paper used by DC in 1940 is slightly higher than that of Timely (Marvel), but remains fragile after 85 years of aging.

CGC Census and rarity

As of the 2026 CGC Census, approximately 800 copies of Batman #1 have been certified. The highest grade is 9.4 (one copy, the "Billy Wright copy"). In 9.0+, less than 5 copies exist. In 7.0+, less than 20. The vast majority of copies are between 1.0 and 4.0, with signs of wear typical of comics read, reread and exchanged by children during the war.

Value by grade

Price history

The record for Batman #1 is $2.2 million (CGC 9.4, Heritage Auctions, 2021). In ten years, prices have doubled to tripled in all grades. Each new Joker project in the cinema revives interest: The Dark Knight (2008), Joker (2019), Joker: Folie à Deux (2024). Even the relative success of these films keeps Batman #1 as a market safe haven.

Advantage of double key issue

The double first appearance (Joker + Catwoman) ensures diversified demand — some buyers target the Joker, others Catwoman, and investors appreciate this double exposure. In comparison, Detective Comics #168 (the Joker's first origin story) or Batman #1 from 2011 (New 52) cannot compete with the appeal of the true first issue. Batman #1 remains the only title that captures the two most famous villains of the DC universe in a single comic.

Points of vigilance when purchasing

For a 1940 comic at this level of value, documented provenance is essential. Systematically check CGC Census and sales history. Restored examples are common at this time — many were retyped in the 1960s and 70s before the notion of "original preservation" existed.

The spine split is the most common and most penalizing defect. Also pay attention to the brittleness of Golden Age paper: a copy that seems correct can lose a grade point if the pages are brittle to the touch. For sales above $100,000, go exclusively through Heritage Auctions, ComicConnect or Goldin — private transactions at this level present significant authenticity risks.
