Lloyd,
Not only have I seen this particular reproduction but I purchased one about six months ago. I, too, spent years searching for a satisfactory copy of the Rodin Mahler bust, and I'd all but given up hope when I finally spotted this one.
It was created by Lillian Vespertino, a young Asian sculptor, and it's done in cast resin mounted on a wood base. The four photographs on the Statue.com Website don't come close to doing it justice. The patina is a much darker brown than shown and it has a light sheen, rather like one of the late Rodin castings (there have been many estate-authorized posthumous castings of both 'A' and 'B' busts with several different patinas), and the wood base is now two-tiered with a darker stain to match the shade of the bust. It would be an easy project to detach the bust and put it on a base of your own choosing, say marble.
I think of it as Vespertino's impression of Rodin's impression of Mahler. She seems to have based it on Rodin's 'B' version—the more realistic of the two bronze busts. I have this reproduction in my living room sitting atop a 45-inch-tall white pedestal so the bust is at the same height Mahler's head would have been when standing. Owning it gives me great pleasure indeed—it's a better copy than I ever expected to find, especially at this price.
