Marvel Team-Up #19

The prehistoric wilds of the Savage Land set the stage for this 1974 Marvel Team-Up, as Spider-Man takes a stunning blow in the foreground while Ka-Zar, Lord of the Hidden Jungle, battles a snapping dinosaur above him — and a second massive reptile looms menacingly in the background. The cover, penciled by Gil Kane and inked by Frank Giacoia, crackles with kinetic energy, teasing the arrival of a wild new threat: Stegron, the Dinosaur Man. Len Wein's story promises exactly the kind of pulpy, action-packed team-up that made this series such a reliable thrill in the Bronze Age of comics.
