Captain Marvel Jr. #69

This January 1949 Fawcett issue features a striking cover by Kurt Schaffenberger showing Captain Marvel Jr. locked in a crackling, lightning-charged struggle with a hulking, bearded convict in a black-and-white striped prison suit — bolts of electricity arcing wildly between them against a fiery orange sky and looming prison walls. A shadowy figure lurks to the left while a guard watches from the tower above, setting a tense jailbreak atmosphere. The banner promises "The Electrifying Human Dynamo," and Schaffenberger's dynamic composition absolutely delivers on that charge.
