For your consideration is this large and interesting sterling silver pin. It has a great abstract modernistic look. The person I got this from believe it was purchased sometime in the 1970s. It is signed Willowbend Sterling. I can't find anything on this maker but it is a cool piece.
It measures 3 and 1/2 inches by 1 and 1/2 inches across the widest points.
It is in excellent functioning condition. The patina is uneven with more on back than front.
