Fighting American #5 (5)

In "Jiseppi the Jungle Boy," Speedboy teams up with Gregory, a timid boy he rescues from bullies, only to find themselves swept into a time-travel mishap when Gregory’s grandfather’s invention sends them 3000 years into the past. Written by Jack Kirby and Joe Simon and illustrated by Kirby with inks by Simon, this 1954 adventure blends youthful heroism with prehistoric wonder. The cover by Jack Kirby captures the moment with dynamic energy, a 10-cent comic that’s a true gem of early superhero storytelling.
