Thor #300 (Marvel, 1980)

Thor has rarely looked more "Mighty" than this! The Norse God of Thunder is surrounded by major players from several pantheons in the Marvel Universe. Featured are several of the Celestials, Zeus, Vishnu, Odin, the Destroyer, the Uni-Mind, and an offering of 12 sacrifices supplied by Mother Earth to save the planet.
This piece has been in the personal collection of Marvel Studios founder David Maisel, who was the Executive Producer on the films Iron Man; Iron Man 2; Captain America: The First Avenger; and of course Thor. Maisel even credits this cover as one of his many inspirations for the Thor film.
