Feature Comics #41

In "Doll Man Joins the Army," the newly minted Lieutenant Ace of Space takes to the skies in the Army Air Corps to stop a daring spy operation targeting a secret flying fortress. Written by Henry Taylor and illustrated by Harry Campbell, this 1941 adventure sees the hero's cover nearly compromised when a battle injury draws a sharp-eyed Major’s attention to a telltale detail—his left arm—hinting at a secret that could unravel everything. The cover, by John Devlin, captures the moment with bold wartime energy.
