Mary Marvel #18

Mary Marvel finds herself in quite the chaotic situation on this November 1947 Fawcett cover, as the World's Mightiest Girl is set upon by a giant green parrot with wings spread wide and not one but two very agitated monkeys — all rendered with lively energy by cover artist Jack Binder. The yellow-and-red burst promises "a riot of thrills, adventures, and laughs," and with a story from writer Otto Binder titled "The Talking Sea Serpent," the fun clearly doesn't stop at the cover.
