Thor Annual #7

This 1978 King-Size Annual pits the Norse Thunder God against an Inca Thunder God "to the death," and Walt Simonson's cover captures that clash with tremendous kinetic energy — two powerful figures straining against each other across a explosive burst of force, while Thor himself looms on the right in full battle mode. Adding even more intrigue, the Eternals hover in the background, and the cover pointedly teases whose side they'll take — plus a promise of "the Soul-Searing Secret of the Third Host" to sweeten the deal. Roy Thomas and Simonson together make this annual a genuinely satisfying oversized package for fans of mythology-driven Marvel adventure.
