Hawkman #23

In "The Hawkman from 1,000,000 B.C.!", Hawkman is thrust into a prehistoric world when Dr. Malevolo’s time machine upends the present, unleashing ancient creatures and sending the hero back to a time when dinosaurs still roam. Written by Richard Hughes and illustrated by Dick Dillin with inks by Chuck Cuidera, this 1967 adventure blends pulp adventure with early sci-fi flair, all captured in a striking cover by Dillin and Cuidera.
