Exquisite Art Deco Crystal Sugar, Creamer and Tray

This is a wonderful quality ribbed crystal covered sugar, creamer, and tray in a ribbed design with a art deco finial on the sugar lid. I believe this is vintage because of the style, but I haven't been able to identify the age or maker. It is of marvelous quality though. The tray is 9.75 by 5 inches. The creamer 3.5 inches high, and 3 and 1/8 inches across the rim. The sugar dish is 4.5 inches tall and 4.25 inches in diameter. All the pieces are in excellent condition. Very bright and clear.
