World's Finest Comics World's Finest Comics was an American comic book series published by DC Comics from 1941 to 1986. The series was initially titled "World's Best Comics" for its first issue; issue #2 (Summer 1941) switched to the more familiar name. Michael E. Uslan has speculated that this was because DC received a cease and desist letter from Better Publications, Inc., who had been publishing a comic book entitled "Best Comics" since November 1939. Virtually every issue featured DC's two leading superheroes, Superman and Batman, with the earliest issues also featuring Batman's sidekick, Robin.
