Captain Marvel Adventures #19
☆ Be the first to review + Add to your collection — Join freeCaptain Marvel Adventures #19 holds a firm place in Golden Age history as the second appearance of Mary Marvel, who had debuted just one issue earlier in #18 (cover-dated December 1942). That rapid follow-up — written by Otto Binder and drawn by Marc Swayze — helped establish Mary as a genuine, recurring member of the Marvel Family rather than a one-off gimmick, paving the way for her solo features in Wow Comics and eventually her own title. The issue also captures the wartime pulse of the Fawcett universe at full throttle: one story pits Captain Marvel against a Nazi scheme involving a Hitler body double, reflecting how thoroughly Fawcett weaponized its characters for homefront morale. Together these elements make #19 a snapshot of a franchise mid-surge, consolidating the Marvel Family's expanding cast while leaning into the patriotic storytelling that defined early-1940s superhero comics.
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.
When eerie phenomena begin plaguing Massey's Department Store—clothes dancing, mannequins moving, and shoppers fleeing in terror—Captain Marvel is called in to stop the mysterious Phantom before the store's Christmas business collapses entirely. Billy and his friend Steamboat find themselves caught in the chaos as Captain Marvel pursues the elusive culprit through the sprawling holiday crowds, only to discover that the Phantom may be far more cunning and human than his supernatural reputation suggests. With the store's fate hanging in the balance, Captain Marvel must unravel the mystery before the Phantom strikes again.
When Nazi spies intercept an encrypted message about an "Achilles heel" weakness in Captain Marvel, they devise a desperate scheme: they'll send a Hitler double to America to rally their operatives, banking on the false hope that the World's Mightiest Mortal can finally be defeated. Billy Batson decodes the plot and transforms into Captain Marvel to confront the enemy—but when the spies capture him, he makes a calculated decision to let them believe they've found his vulnerability, all while waiting for the real prize to arrive.
When Silent Sam, the tire thief, hits Swatville hard—stealing dozens of rubber tires in just two days—Captain Kid spots the crook in action and gives chase, only to have things go spectacularly sideways. Betty Mae witnesses the chase and is furious at Captain Kid for letting the thief escape, leaving our hero not only embarrassed but heartbroken. With his girl disgusted and his own tires stolen, Captain Kid is determined to catch Silent Sam and set things right.
In "The Ego Exchanger," Billy Batson and Steamboat find themselves caught in a bizarre twist when a mysterious device swaps their minds—each taking the other’s body while retaining their own thoughts. With Steamboat now in Captain Marvel’s form and Billy trapped in Steamboat’s, the usual heroics take a comical turn as they navigate their mismatched lives.

The issue carries a cover date of January 1943 and, per copyright-entry records, went on sale in December 1942 — specifically documented as December 9 or 11, 1942 depending on the source. Writing duties fell almost entirely to Otto Binder, who by this point had been scripting Captain Marvel material since 1941 and would go on to write, by one contemporary count, well over half of the entire Marvel Family saga across his Fawcett tenure. The cover was penciled by Marc Swayze, and a 2017 article by comics historian P.C. Hamerlinck in Alter Ego established that Swayze also handled the complete interior art on the Mary Marvel story — correcting an older, erroneous attribution. C.C. Beck and Pete Costanza contributed art on the remaining Captain Marvel stories, with Al Liederman handling the Captain Kid backup.
