Unmarked Bauer vintage cup in a green/teal type color that I think was called jade. This is a different pattern of ring type ware with two separate sets of concentric circles.
It has a few pinpoint glaze specks, but no cracks - a small rub wear discoloration spot. I don't see a marking on the bottom but it has the Bauer mold marks and horizontal center line. Approx 2.5 inches tall
Buyer to pay shipping. I will package carefully in a box and ship promptly.
