Edgar Rice Burroughs' Tarzan #114

Deep in a lush jungle setting, this Dell cover by Morris Gollub captures Tarzan — knife clenched in his teeth, rope in hand — facing down a snarling leopard perched on a gnarled tree trunk. The tension between man and big cat is rendered with striking naturalism, the dense green canopy framing the standoff beautifully. Inside, writer Gaylord Du Bois and artist Russ Manning bring Edgar Rice Burroughs' Lord of the Jungle to life in "Valley of Lions," making this 1959 issue a fine showcase of Dell's Tarzan at its adventurous best.
