Superman #315

A villain in green and purple crashes through shattering glass to confront Superman on this striking September 1977 cover, boasting in bold speech bubbles that he's stolen the Man of Steel's identity and now calls himself Clark Kent. The cover's headline teases a new hero of Metropolis called Blackrock, suggesting Superman's reputation is already under siege before the fight even begins. With cover art by Al Milgrom and Jack Abel, and a story from Martin Pasko with interior art by Curt Swan and Dan Adkins, this issue promises a sharp identity-crisis thriller straight from DC's Bronze Age.
