Sunday is Monkey Covers day here at YACB. Because there's nothing better than a comic with a monkey on the cover.
Here's Brian Bolland's cover to 1987's Swamp Thing Annual #3 featuring Congorilla, from a story by Rich Veitch that featured not only Congorilla, but also Angel & Ape and Grodd.
(Standard disclaimer about golden gorillas not really being monkeys applies.)
