Batman #3

Batman #3 was published by DC Comics in the fall of 1940. This issue arrived during the formative years of the character, a period defined by the creative partnership of writer Bill Finger and artist Bob Kane. At this stage in the Golden Age, the series was rapidly expanding the Dark Knight's rogue's gallery and formalizing the tropes of the vigilante detective genre that would define the medium for decades to come.

The issue is particularly noted for the introduction of Catwoman, originally referred to as 'The Cat.' Designed to serve as a recurring antagonist and a moral foil to Batman, the character's early aesthetic and personality reflected the high-glamour, pulp-noir influences prevalent in the 1940s. While historical records regarding the specific creative contributions of early DC staff are often complex, the issue remains a cornerstone of comic book history for its role in solidifying the supporting cast that transformed Batman from a simple crime-fighter into a cultural icon.
