World’s Finest featured Superman and Batman team-ups until issue #197. Noted Batman artist Neal Adams first drew the character in an interior story in “The Superman-Batman Revenge Squads” in issue #175 (May 1968). The title briefly featured Superman teaming with heroes other than Batman in the early 1970s beginning with issue #198 (November 1970). That issue featured the first part of a two-issue team-up with the Flash. The series reverted to Superman and Batman team-ups after issue #214, initially with a unique twist, featuring the children they might one day have, Superman Jr. and Batman Jr. These characters, billed as the Super-Sons, were co-created by writer Bob Haney and artist Dick Dillin in issue #215 (January 1973).
