Master Comics #38

Master Comics #38 (May 1943) puts Captain Marvel Jr. front and center in a striking cover by Mac Raboy, depicting the purple-and-yellow costumed hero soaring triumphantly atop a massive torn steel girder ripped from a Japanese Imperial Navy warship below, red enemy aircraft scattered across its deck. The tagline "America's New Secret Weapon" captures the wartime energy that made Fawcett's hero titles resonate so strongly with 1943 readers. Raboy's fluid linework and confident sense of motion make this a genuinely arresting piece of Golden Age cover art.
