Captain Marvel Jr. #49

This 1947 Fawcett gem captures Captain Marvel Jr. in a wonderfully surreal situation — a sleeping Freddy Freeman lies in the foreground while his caped alter ego faces off against a towering, green-skinned horned monster amid swirling dream clouds above. The cover by Bud Thompson does a fantastic job of blending the eerie and the adventurous, teasing the issue's story, "The Dream Recorder," with a scene that makes the boundary between sleep and super-heroics feel delightfully unstable.
