This striking egg cup is made of porcelain and hand painted in slate blue with a silver border and foot. On the underside is a signature of one C.S. Thompson dated 1923, which makes it a rather unique egg cup in that it appears to have been made by an individual rather than manufactured. It stands 2 3/4" and is 1 3/4" in diameter and is in fine condition. A nice addition to your collection of egg cups!
