Tarzan Legacy

I've begun reading my grandfather's Tarzan books; starting with I think the first one, "Tarzan of the Apes." It starts with Tarzan's parents and his adoption by Kala of the Apes (1914). The book has a note written inside from a friend of my grandfather dated November 1916. At that time grandpa would have been 13. The books were read by my father (and recently read again by him). I have begun reading these myself and I hope to give them to my son who loves reading. One interesting side-note, Grandpa Dubs would be 113 if he was still alive. I still remember when he gave the books to me prior to his death in 1981. He (correctly) told me that he thought I would value them.
