TARZAN THE INVINCIBLE
Africa, the hunting ground of savage beasts, primitive men, and the hidden fragments of ancient civilizations, was the target of a clever Red scheme to create chaos and take it over.
It was in the oldest ruins of all, the lost city of lost Atlantis, Opar, that this newest of world conquerors chose to make the point of attack.
There was only one defender of freedom who knew the location of Opar and that was Tarzan of the Apes. And so the contest of wits and skill and jungle cunning was met—to make TARZAN THE INVINCIBLE one of Edgar Rice Burroughs' best.
