Captain Marvel Adventures #22

From 1943, this Fawcett wartime issue puts Captain Marvel front and center in his bold red-and-gold uniform, grabbing a dark-clad saboteur by the collar high above an industrial shipyard — the cover text leaves no doubt: "Captain Marvel Battles Shipyard Sabotage!" The dynamic cover, penciled by C. C. Beck and inked by Pete Costanza, captures the World's Mightiest Mortal mid-action with the kind of confident energy that made this title proudly boast the largest circulation of any comic magazine. As a bonus, the bottom banner announces the start of a brand-new Captain Marvel mystery serial — plenty of reason to flip past that striking cover.
