Captain Marvel Jr. #64

When superheroes meet the Wild West, sparks fly — and this August 1948 Fawcett issue makes that literal, with bullet impacts kicking up dust and flame around a rearing white horse. Kurt Schaffenberger's cover pits Captain Marvel Jr. in full blue-and-gold uniform against a masked, bandana-wearing outlaw on horseback, the villain's pistol leveled even as the young hero surges forward through a burst of smoke. It's a vivid genre mashup that promises exactly what the cover text delivers: wild west action as Capt. Marvel Jr. clashes with the Outlaw.
