Edgar Rice Burroughs' Tarzan #21

This May-June 1951 Dell issue features a striking photo cover of Lex Barker as Tarzan, knife in hand, crouched alertly amid jungle foliage while three great apes surround him — one peering from the left, two more perched in the branches above. The tension of the jungle lord's watchful gaze makes for a vivid, immediate cover that bridges the world of film and comics in a way unique to this era. Inside, Gaylord Du Bois and Jesse Marsh deliver a full 52 pages of all-comics adventure, including "Tarzan Returns to the City of Gold.
