Start here and follow the internal linkshttp://www.pipephil.com/article-2775903.html for the full story on the Tarzan pipe. It's written in French, so you'll probably need the Google translator.
The skin is reportedly leopard (Panthera pardus), but IMO it could easily be artificial. I dunno. The stamping on the "leather" purportedly says TRC Savvage, but I'm gonna check some old Iwan Ries (IRC) catalogs to see if they ever sold a Savvage line of pipes. At any rate, the picture of Tarzan with a pipe seems pretty unambiguous.
It has to be Sherlock Holmes. Ask anyone who is the most famous pipe smoker and that will be the answer.
I watched the "new" Sherlock Holmes movie on blueray last saturday and it was really great although not with enough pipe smoking. Can't wait for the next one.
