I don't see a mark on this, but believe is it is Walter Bosse, and an early one, with the original gilding to the nose and paws pretty much gone. I love it more for the wear, and that believe that it is bronze. I like by the sink as a ring holder, though it could certainly hold one's morning hard boiled egg.
2 3/4" l x 1 3/8" w x 3/4 t and in good condition, with loss to the gold details as noted but a nice patina.
