Marvel Two-in-One Annual #2

This 1977 king-size annual pairs the Thing and Spider-Man against one of Marvel's most formidable cosmic threats, and the cover by Jim Starlin says it all — Thanos towers at center, physically dominating both heroes while a glowing, ethereal face looms ominously in the background. Flanking the main image are portrait heads of the supporting cast: Thor, Captain America, the Vision, Scarlet Witch, Iron Man, and more, confirming the Avengers and Captain Marvel are along for what the cover boldly promises as "The Epic Villainy of Thanos." Starlin, who both writes and draws "Death Watch!", is in his element here, bringing genuine cosmic scale to a team-up that earns every bit of its king-size billing.
