Greyish white with some drippy glaze in spots. This is a skirt rest triple petticoat Pittsburg. No date stamp visible in this case but part of a fingerprint (small) can be seen on the crown. Excellent shape with only two small hairlines on the base mostly of which can't be seen. Not 100% sure on the U number but whatever it is it's an unusual design and an eye appealing color. $55 pp. Thx
