This is a Beautiful antique wash basin and pitcher set made by W & C Co. It is back stamped.
The pitcher is ~10.0” (W)x8.2”(D)x11.3”(H), and The basin is ~15.9” (W)x4.1”(H). They are both in excellent estate conditions with no chips, cracks or repairs. Just Some wears and crazing on both pieces consistent with their age, and a few production flaws. Zoom in and make judgment.
