Vintage Signed Coro Unusual Christmas Brooch Pin retailer Bells

Up for sale is a vintage signed Coro brooch retailer pin that is unusual and beautiful. I've never seen one like it before. It is a Christmas or winter holidays pin. It has 3 enameled oak leaves. No enamel is missing. Then it has 2 shiny silver acorns. The best part are the bells. It has 3 red dangling bells hanging from the bottom. If you look closely they have an embossed pattern on them. Each still has the clapper inside. Marked Coro on the back. 2 inches long and 2 inches wide. It looks to be in perfect condition. I don't see a thing wrong with it.
