The art glass is unmarked, but its originality is confirmed by its early 20th-century era and art glass production style. The decorative features of this piece are sure to catch the eye of any admirer. It was made in the United States and is a rare find for collectors of decorative glassware. This item would make a great gift for anyone who appreciates vintage glassware and wants to add a unique piece to their collection. This item could use a clean. There is sticker residue on it. Some goo gone would probably do the trick. No discounts after sale.
