This large Higgins ashtray in the Barbaric Jewels pattrern is trapazoidal in shape. The width on one end is 10" tapering to 8", while the length tapers from 12" ro 11 1/2". It is 1 1/2" high. It is of clear glass and features colored "jewels" of glass surrounded by gold fired on medallions of design. This one was commissioned as a gift for Pittsburgh Plate Glass execs and features one medallion which consists of the PPG logo surrounding a "jewel". An altogether stunning piece.
