Vintage Signed Beau Sterling Carved Celluloid Rose Brooch Pin 1940s

Vintage Signed Beau Sterling Carved Celluloid Rose with lightly enameled green leaves Brooch Pin 1940s. Beautifully detailed and in great condition for its age. I do not see any chips in the rose. There is some tarnishing on the back of the leaves. Measures 1 7/8” X 2”. (The back of this piece is not black, I had to cast a shadow in order to show the stamp.)
