Superman's Pal, Jimmy Olsen #120

Few Silver Age covers pack a gut-punch quite like this one: Superman lies motionless on the ground while a stunned Jimmy Olsen recoils in disbelief and a doctor presses a stethoscope to the Man of Steel's chest, delivering the unthinkable verdict — "Superman is dead! You killed him, Olsen… with one punch!" The cover art by penciler Curt Swan and inker Neal Adams sells every ounce of shock and anguish in that scene, making it impossible not to flip to page one. Featuring the story "Jimmy Olsen's Super-Punch!" with interiors by writer Leo Dorfman and artist/inker Pete Costanza, this June 1969 issue of Superman's Pal, Jimmy Olsen is a wonderfully wild example of the era's knack for irresistible, impossible-sounding dilemmas.
