Tales of Suspense #58

From 1964, this issue of Tales of Suspense poses a question that's hard to resist: why are two of Marvel's mightiest heroes locked in all-out battle? The cover by Jack Kirby and Chic Stone delivers the spectacle in full — Iron Man's red-and-gold armored form trading blows with Captain America, whose star-spangled shield crackles with impact energy between them, machinery looming in the industrial background. The cover copy even winks at readers with cheerful honesty, admitting the fight is "mainly to get you to buy this mag" — and six decades later, that straightforward charm still works perfectly.
