This listing is for a lot of 12 antique mother of pearl shell buttons on their original "Bluebird Pearl Buttons" card, dated 1923. The buttons measure 1/2" diameter. They are in very good condition, card has a little wear on the corners. A nice addition to your collection or to add to a special project. Check out the other buttons I have listed, I will gladly combine purchases, each additional button lot purchased adds 50 cents to the shipping cost.
