Sunday is Monkey Covers day here at YACB. Because there's nothing better than a comic with a monkey on the cover.
We're Lost in Space with the Robinson family as they take on a giant four-armed cycloptic gorilla on the cover of Space Family Robinson #59.
(Standard disclaimer about giant four-armed cycloptic gorillas not really being monkeys applies.)
