Edgar Rice Burroughs' Tarzan of the Apes #182

In "Tarzan the Invincible, Part 1," Tarzan returns from Pellucidar to confront a dangerous coalition of natives, Arabs, and two Russian communists—Peter Zveri and Zora Drinov—intent on raiding the fabled city of Opar for its gold to fund a radical African revolution. As Tarzan races ahead to Opar, he discovers the rightful queen, La, imprisoned by the usurper Oah, while Zora is rescued from a Hindu assassin by the unexpected American Wayne Colt, who’s unaware of Zveri’s true agenda. Written by Edgar Rice Burroughs and Gaylord Du Bois, with art by Doug Wildey and cover by George Wilson, this 1969 Western Publishing adventure blends jungle intrigue and Cold War tension in a gripping first chapter.
