Action Comics #378

Action Comics #378 (July 1969) presents a genuinely unsettling cover as a sinister, bald villain holds a tiny Clark Kent voodoo doll over flames, forcing a grimacing Superman to cry out in pain — with the demand that the Man of Steel swear to become his partner in evil. The cover pencils by Curt Swan and inks by Neal Adams give the scene a dramatic intensity, with the firelit backdrop and Superman's anguished expression selling the threat perfectly. Featuring the story "The Devil's Partner!" with interior work by Swan, inker Jack Abel, writer Jim Shooter, and letterer Ben Oda, this is a fine example of late-Silver Age DC storytelling at its most imaginatively sinister.
