Marked on back Beaucraft Ster and copyright symbol. Excellent condition, measures just under 2 1/2 inches tall, about 1 inch wide at widest, and weighs 7.7 grams. Beau sterling made many of these modernist cats in different designs, this one is a little harder to find in this condition and with the larger eyes. Love to wear a couple of these designs together they are so nice and everyone notices them. I have always been a fan of Beau ever since my first piece back in the early 1980's of two horse trotting side by side. I marvelled at their amazingly detailed and unique designs way before anyone who was collecting name pieces of jewelry noticed them. Beautiful brooch, you'll love this one in your collection too!
