Spectacular Sinclaire glass vase in purple. This is a wonderful example in excellent condition. No chips, cracks, repairs or damage. The bottom has a smoothly polished pontil mark with an acid stamped "S". I understand that Sinclaire only produced colored glass for 3 years in the 1920's. It measures 5 1/8" in height, 3 1/8" in top diameter, 2 3/4" base diameter. A very fine example for your glass collection.
