Kamandi, the Last Boy on Earth #5

Kamandi faces impossible odds on this 1973 DC cover penciled by Jack Kirby and inked by Mike Royer — the blonde, dual-dagger-wielding Last Boy on Earth squares off against a massive, snarling gorilla in green armor while a crowd of armored ape soldiers watches from the sidelines at Murdock Air Field. The dialogue crackles right on the cover itself, with the apes declaring "the yellow-haired animal" must die, setting a tense gladiatorial stage for Jack Kirby's story "The One-Armed Bandit!" This is Kirby's post-apocalyptic world at its most vivid: a lone human boy, outnumbered and outmatched, refusing to back down.
