This is an outstanding, classically formed wine taster that dates from the art deco period. Christofle's premiere, high-end (quadruple plated) silverplated collection was the "Gallia" collection and this piece is so marked (see photo). The French firm of Christofle is noted for their superior crafstmanship and design. The hallmarks are quite clear in the last photo. The taster measures approx 3 1/8" in diameter and 4 1/4" to the end of the thumb rest but not including the thumb Rest and is 3/4" deep.
