Edgar Rice Burroughs' Tarzan #107

Dell's long-running Tarzan series brings an air of genuine mystery with this August 1958 issue, promising "The Mysterious Valley of Monsters!" The photo cover features a powerfully built, bare-chested Tarzan crouching alertly beside a mossy rock at the water's edge, his steady gaze suggesting a man entirely at home in dangerous terrain. With Gaylord Du Bois writing and Jesse Marsh handling the interior art, it's a solid entry in one of Dell's most enduring adventure titles — and at a dime, it was quite the deal.
