Captain Marvel Adventures #19

In "The Phantom of the Department Store," a 1943 adventure from Captain Marvel Adventures #19, the legendary duo of Mary and Billy (as the Marvels) take on a cunning fraud when a self-proclaimed Venusian explorer named Greaseley pulls off a dazzling deception in a department store. Written by Otto Binder and brought to life with dynamic art by Marc Swayze—both interior and cover—this classic tale blends pulp intrigue with the heroics of Fawcett's golden age stars.
