Vintage Beau Sterling Silver Pin Brooch - Mid Century Modern Design

From Beau aka Beaujewels and dating to the 1950s/1960s or so, here's a Sterling Silver (hallmarked as pictured) pin/brooch in a highly stylized modernist design. The pin measures 1-5/8" x 1". Weight is 3.5 grams. Safety catch at the back to hold the pinstem in place. Some light surface marks to the front that a professional polish will make disappear! An interesting design from a well known name in mid century jewelry.
