Avengers, Volume 1, Issue #191

From the January 1980 issue of the Avengers :

Scarlet Witch, the Wasp, and Ms. Marvel all get KOed by the Grey Gargoyle! The Wasp scene is pretty much worthless, due to her tiny size, but the scenes with Wanda and carol are very good. The two full-size heroines are depicted unconscious and there is a nice wake-up scene.
