Scarce promotional children's book issued by Gimbel Brothers for Philadelphia's pioneering WIP radio station during the infancy of commercial broadcasting. Published to accompany the station's popular "Uncle WIP" children's programming, the book introduces readers to the whimsical inhabitants of "Castle Broadcast," an imaginative fantasy world created for young radio listeners. An engaging survival from the earliest years of American radio, combining children's literature with one of the first successful department store broadcasting ventures.

Illustrated with 8 full-page color plates on glossy stock and numerous in-text drawings credited to O. P. Arouse. Castle Broadcast is populated by a memorable cast of talking animals, fairy-tale creatures, and adventurous companions—including the Scarlet Bird and Big Brown Bear—whose exploits carried the magic of WIP's children's broadcasts from the airwaves to the printed page. An attractive and increasingly elusive survivor from the formative years of American radio.
