Giant-Size Spider-Man #4

Spider-Man and the Punisher share the spotlight in this 1975 oversized team-up, with the web-slinger bursting through barbed wire fencing toward the reader while the skull-chested Punisher advances alongside armed soldiers in the background. The cover, penciled by Gil Kane and inked by Frank Giacoia, captures the tension of two very different heroes joining forces — as the tagline puts it, "the Wonderous Web-Slinger and Gangland's Executioner join forces to save the world!" Inside, Stan Lee and Steve Ditko deliver a full 68 pages titled "To Sow the Seeds of Death's Day!" — plenty of room for this unlikely alliance to play out.
