Vintage BEAU Sterling Silver Lobster Pin Brooch

Dating to the 1960s or so and crafted by Beau, here's a Sterling Silver (hallmarked as pictured) pin/brooch in the shape of a lobster. Good strike to the design. Length is 2-1/4"; height is 1". Weight is 3.9 grams. Safety catch at the back to hold the pinstem in place. Very nice condition with a mellow patina to the silver.
