Marvel Team-Up #13

Spider-Man and Captain America charge side by side through a machinery-filled industrial setting on this September 1973 cover, with Cap's shield raised and Spidey's fists ready — and the menacing face of the Grey Gargoyle looming in the lower corner, flames erupting all around them. The cover by Gil Kane and John Romita crackles with forward momentum, promising exactly what the blurb delivers: two of Marvel's mightiest heroes in non-stop action together. "The Granite Sky!" sounds like a tense team-up, and this early Marvel Team-Up entry captures the genuine excitement of pairing two very different heroes against a formidable shared threat.
