Based on its wonderful patina and delicate features, I believe the piece I have here is one of the later (1927 or later) Roman Bronze Works pieces. The piece was cast in real bronze and is heavy. It and is an old piece.
The piece, in various states, is included in the collections of the Amon Carter Museum, the Sid Richardson Museum, the Smithsonian Institution. A first state example sold at auction for $ 72,800
