The Avengers #174

The Collector looms menacingly in the foreground of this George Pérez and Terry Austin cover, his weathered face set with cold determination as he operates a control panel that sends crackling energy beams tearing through Earth's Mightiest Heroes. Thor, Iron Man, Captain America, Scarlet Witch, and more Avengers are scattered and staggered by the assault, while Hawkeye leaps into action overhead and Vision hovers at the upper left — the full roster caught in a desperate struggle against one of Marvel's most cunning Elder of the Universe. With a story title of "Captives of the Collector!" and a lineup this packed, the August 1978 issue promises a team-wide showdown that makes for a thoroughly satisfying piece of late-Bronze-Age Avengers storytelling.
