Marvel Mystery Comics #56

From the wartime summer of 1944 comes this vivid chapter in Marvel Mystery Comics, featuring a cover by Alex Schomburg that crackles with patriotic urgency. The scene bursts with a fiery, flame-streaked figure delivering a blazing strike against a villain in purple beneath a looming Nazi swastika emblem, while captured figures and frantic enemy agents fill the chaos of what appears to be a sinister underground lair. With a story titled "Berlin's Master Spy" and Jimmy Thompson bringing the interior art, this issue captures the full-throttle spirit of Golden Age superhero comics at their most charged.
