The listing, Cute Brooch Kitten in Basket with Ball of Yarn Sweet Pin - stamped JJ has ended.
This is a very cute pin (brooch) to wear on your blouse, sweater, dress, etc. Not sure what it is made of, looks a little like pewter but could be some other metal. It is stamped on the back J.J. I assume that is the creator/artist. Could be the manufacturer. I don't know too much about these things. Bought it at an estate sale a few years ago. It's about 3" long with the dangling ball of yarn. The yarn is actually some type of close link chain, so it swings independently. Super cute!
