Master Comics #52

This July 1944 Fawcett publication brings together two of the publisher's stalwarts — Captain Marvel Jr. and Radar, the International Policeman — in a cover rendered by Al Carreño that doubles as a wartime public service message. The two figures are shown holding up an oversized United States War Savings stamp valued at one dollar, with the bold call to action "Buy One of These War Stamps Today!" making clear that even superheroes were doing their part on the home front. Inside, the duo heads into adventure with "The Swiss Misadventure," promising globe-trotting intrigue that suits Radar's worldly reputation perfectly.
