I bought the piece at a very reasonable price, much lower than is being asked for similar pieces on E-bay and elsewhere.
I wasn't, originally, aware that it is an "homage" piece, or rough copy, of a famous sculpture by 19th century German sculptor
Wolfgang Hugo Rheinhold
(26 March 1853 – 2 October 1900) who was arguably most famous for his
Affe mit Schädel (Ape with Skull), inspired by Charles Darwin's theory of evolution. There have been several variations, copies of, and tributes to Rheinhold's sculpture over the years. Austin Productions was one of the original US manufacturers. The Austin Productions piece differs from Rheinhold's original in fine detail, and in material used.
