Nickel Comics #2

In "Who Is Bulletman?", the mysterious crimefighter known as Bulletman races to stop Blackmask from exploiting the deadly freezing-gas formula left behind by the late Dr. Denton. When Bulletman himself falls victim to the gas, it's his secret identity that holds the key to the cure. Written by Bill Parker and illustrated by Ed Smalle, with a striking cover by Jack Binder, this 1940 Fawcett classic blends pulp intrigue and early superhero mystery in a story that sets the stage for the hero’s true origins.
