Kamandi, the Last Boy on Earth #4 (DC Comics, 1973)

Kirby had revolutionized DC mythology with his Fourth World epic and related titles, but his long-running futuristic serial, Kamandi (and to a lesser degree OMAC), created a lasting vision of DC's far-flung future. Kirby produced more original material for Kamandi than for any of his other DC titles of the period, 40 issues containing Kirby stories. The inks are by Mike Royer, who famously partnered with Kirby during his DC stint in the early 1970s. This is one of Kirby's most recognizable images of that time, having been used as the cover for The Jack Kirby Omnibus Kamandi hardcover book.
