One of my favorite ads for Marvel Comics was the subscription page that appeared in issues with cover dates of Nov. 1981, Dec. 1981, and Jan. 1982 (Defenders #101, #102, #103). While the titles listed on the subscription form included science fiction, jungle adventure, and sword and sorcery themes, the illustration accompanying the ad was a superhero sight gag reminiscent of the humor magazines that Marvel would publish at various points.
Pictured in the ad, a tiny Ant-Man tries to outrun the Hulk, who has just stepped on Iron Man. Meanwhile, Giant-Man busts through the roof of the heroes' comedically overcrowded clubhouse. Several other characters are only partially visible yet still recognizable by their claws, tail, winged ankles, or other identifiable traits.
