Captain Marvel Jr. #52

High above a city skyline, Captain Marvel Jr. soars alongside a wide-eyed postman clutching his mail bag — the cover promising their unlikely aerial adventure together in "Captain Marvel, Jr. and the Flying Postman." This August 1947 Fawcett publication captures the lighthearted charm of the era, with the young hero's red-and-gold costume cutting a confident figure against billowing clouds as the bewildered letter carrier tumbles through the skies beside him. With interior work by writer Otto Binder and artist Bud Thompson, it's a wonderfully offbeat slice of golden-age adventure for any fan of the era.
