Tarzan #21

In "The Land of Awful Shadow," Tarzan faces a dire threat as the Mahars unleash their sound cannon, decimating half the Pellucidar army. With tensions rising, the Cid uncovers a shocking betrayal—Frazier, not Tarzan, was behind the theft of his treasure. Written by D. Kraft and B. Mantlo, with art by Sal Buscema and inks by Rudy Nebres, this 1979 Marvel adventure delivers pulse-pounding action and shifting loyalties. The cover, penciled by John Buscema and inked by Bob McLeod, captures the perilous mood of the jungle’s darkest hour.
