Interesting. Is this set before or after Dark Horse's series where Tarzan went to Barsoom?
Professor Porter, Jane's father, is still alive at the time of his story. Farmer placed the Professor's death in 1927 in Tarzan Alive. So it must take place before that year, though it seems to be set in the 1990s. Of course, we can chalk that up to fictionalization.
