Developed for Harvey's short-lived superhero line, Harvey Thriller, Jigsaw was the disconnectable "Man of a Thousand Parts". The feature was drawn by Tony Tallarico, with the writing generally, if unconfirmably, credited to Otto Binder. The backup features were "Super Luck" in issue #1 (artist unknown) and "The Man From SRAM" (art by Golden Age veteran Carl Pfeufer) in #2. The first issue also featured an anthological science fiction story drawn by EC Comics great Reed Crandall. Work for a third issue may exist.
