Here we have a young boy child bust figurine. It looks like it may have been a casting/master mould that would have been used to make a bronze/cast bust.  It looks to be made from plaster. It has a green/bronze/patina paint coating which may have been added later and then sold on. The cast is based on Francois Duquesnoy "Child" bronze bust. It has a great raw look. It is fairly quite rare as these would have usually been thrown away.
