The listing, Vintage United Auto Workers UAW Pin with Rhinestone has ended.
Up for bid is a vintage UAW CAP pin in good condition! I think the CAP stands for Community Action Program (Googled it). Pin is probably meant for a lapel, hat, or possibly a tie tac.
Measures approximately 3/8" x 9/16". Has flower logo on back of pin, and I haven't identified the company.
Gold rimmed with dark royal blue enamel, and a rhinestone in the center. Push-pin back clasp. I tried to enlarge the scan, since it's so small, but that just made the picture blurry. So, sorry for the poor view.
It's tiny but neat! If you collect Union pins, this is a nice one for your collection!
