Sunday is Monkey Covers day here at YACB. Because there's nothing better than a comic with a monkey on the cover!
Gorilla Grodd and the rest of the Secret Society of Super-Villains loom over the heroes on the cover to DC Special Series #6 (1977) by Rich Buckler & Jack Abel.
(Standard disclaimer about world-conquering gorillas not really being monkeys applies.)
