Tales of Suspense #56

From 1964 comes this riveting chapter in Marvel's Tales of Suspense, featuring Iron Man squaring off against the Uncanny Unicorn in what the cover boldly promises is a "never-to-be-forgotten battle." Jack Kirby and Dick Ayers deliver a charged cover scene: Iron Man absorbs a blast from the helmet-horned villain while a frightened young woman is caught between them in a stylishly rendered living room. Stan Lee and Don Heck bring the story inside, and the cover teases an unusually character-driven tale — promising new insight into Iron Man himself alongside the high-voltage action.
