What DC Comic book did the Joker originally appear in 1940?
Joker (character) The Joker is a fictional supervillain created by Bill Finger, Bob Kane, and Jerry Robinson who first appeared in the debut issue of the comic book "Batman" (April 25, 1940), published by DC Comics. Credit for the Joker's creation is disputed; Kane and Robinson claimed responsibility for the Joker's design, while acknowledging Finger's writing contribution. Although the Joker was planned to be killed off during his initial appearance, he was spared by editorial intervention, allowing the character to endure as the archenemy of the superhero Batman.
Dick Sprang Richard W. "Dick" Sprang (July 28, 1915 – May 10, 2000) was an American comic book artist and penciller, best known for his work on the superhero Batman during the period fans and historians call Golden Age of Comic Books. Sprang was responsible for the 1950 redesign of the Batmobile and the original design of the Riddler, who has appeared in film, television and other media adaptations. Sprang's Batman was notable for his square chin, expressive face and barrel chest.
