Batman (comic book) work, and first interior-story work, appeared in "Batman" #19 (Oct.-Nov. 1943), for which he drew the cover and the first three Batman stories, and penciled the fourth Batman story, inked by Norm Fallon. Like all Batman artists of the time, Sprang went uncredited as a ghost artist for Kane. Villains which debuted during this early era included the Mad Hatter in issue #49 (October 1948) and Killer Moth in issue #63 (February 1951). In 1953, Sheldon Moldoff became another one of the primary Batman ghost artists who, along with Win Mortimer and Dick Sprang, drew stories credited to Bob Kane,
Bob Kane from DeWitt Clinton High School and then legally changed his name to Robert Kane. He studied art at Cooper Union before "joining the Max Fleischer Studio as a trainee animator in the year of 1934". He entered the comics field two years later, in 1936, freelancing original material to editor Jerry Iger's comic book "Wow, What A Magazine!", including his first pencil and ink work on the serial "Hiram Hick". The following year, Kane began to work at Iger's subsequent studio, Eisner & Iger, which was one of the first comic book "packagers" that produced comics on demand for publishers
