Vintage Silver Tone Costume Jewelry Bowling Ball & Pins Brooch Pin

A Vintage Silver Tone Bowling Ball & Pins Pin. Measures about 1 1/4" in height. It's marked, but I can't read it. CONDITION:  In nice shape, though vintage and used, so not pristine or perfect. Some surface scratches, discoloration and oxidation, and some general signs of age and wear. I purchase all of my items at auctions, so cannot be sure of their history or whether they've come from smoke-free or pet-free homes.  I do my best to list any damage or use, but I'm not an expert.  So if there's something specific you need to know before bidding, please ask. Payment (by PayPal) is due within three days.  Thank you!
