Captain Marvel Jr. #21

A wartime gem from Fawcett's 1944 lineup, this issue features a cover by Mac Raboy showing Captain Marvel Jr. soaring in his blue-and-gold costume, red cape streaming behind him as he presents a United States War Savings dollar stamp — a Minuteman soldier depicted on its face — with a cheerful call to "Buy One of These War Stamps Today!" It's a vivid snapshot of how superhero comics threw their full enthusiasm behind the home-front effort during World War II. Inside, Otto Binder's story "Heroes Never Quit!" promises the kind of determined, never-say-die spirit that made this young hero one of Fawcett's most appealing characters of the era.
