The company's most successful superhero series was Super-Mystery Comics featuring Magno the Magnetic Man and his boy partner Davey. Horror titles included Baffling Mysteries, Hand of Fate and Web of Mystery. Their contribution to the crime comics genre was Crime Must Pay the Penalty. Some of their longest running series were the four romance titles Glamorous Romances, Love At First Sight, Love Experiences, and Real Love. The romance titles began in the late 1940's, after the superhero books faded in popularity, and continued until the company ceased publishing comic books in 1956.
