Tarzan and the Tarzan Twins is a collection of two Tarzan novellas for younger readers. It was originally published as two children's books, The Tarzan Twins in October 1927, and Tarzan and the Tarzan Twins, with Jad-bal-ja, the Golden Lion in March 1936. These were brought together in November 1963 under the title of Tarzan and the Tarzan Twins in the first complete edition.
The Tarzan Twins, Dick and Doc, were born on the same day and resembled one another quite closely. Then, one day, they received a letter from Tarzan of the Apes, inviting them to visit him in Africa. When their parents were unable to travel with them, and after intense appeals, the boys were to go to Africa alone, to meet Tarzan and fifty of his Waziri warriors at the end of the railway. However, Dick and Doc became lost in Africa before that fateful meeting!
