Sunday is Monkey Covers day here at YACB. Because there's nothing better than a comic with a monkey on the cover!
Tarzan leaps in to save a chimpanzee from a bunch of battling baboons on the cover of Lord of the Jungle #1 (2012) by Ryan Sook.
(Standard disclaimer about neither chimpanzees nor baboons not really being monkeys applies.)
