Spillane soon began writing an eight-page story every day. He concocted adventures for major 1940s comic book characters, including Captain Marvel, Superman, Batman, and Captain America. In the early 1940s, working for Funnies, Inc., he wrote two-page text stories which were syndicated to various comic book publishers, including Timely Comics. At one point, Spillane estimated he wrote fifty of these "short-short stories," which were intended to fulfill a postal regulation requiring comic books to have at least two pages of text to qualify for a second-class mailing permit.
