Kamandi, the Last Boy on Earth #31

Kamandi — the lone blond boy in tattered clothes — braces himself against a colossal, rocky giant whose enormous fist looms over him, while a squad of armed, humanoid tiger soldiers charges in from behind. Jack Kirby and D. Bruce Berry's cover for this July 1975 issue perfectly captures the wild, post-apocalyptic scale of "The Gulliver Effect!," pitting one small human against an overwhelming world. It's a vivid snapshot of everything that made this DC series such a compelling trip into tomorrow's strange Earth.
