 This is Buster Crabbe (qv)s last appearance in a serial in a  loincloth. He was playing the part of Thunda, a character owned by  Magazine Enterprises. Thunda is the only Tarzan clone to ever  feature in a serial; Frank Frazetta did the art for his origin  story, a story that appeared in "Thunda, King Of The Congo #1".  Ironically, ThunDas comic book run only lasted six issues.
