APPRAISER: Quezal is a New York glass company. Uh, it was formed by Martin Bach, who was a chemist for Tiffany's. And after a while, he left Tiffany's, and he opened up the Quezal Glassworks in Brooklyn, New York. Now, Tiffany wasn't happy, because he had access to all Tiffany's styles and designs, and foremost for the glass. So the form is actually known as a Jack-in-the-pulpit or a lily vase. The signature is on the bottom of the piece, and it's Quezal. And it's like a black penciled mark. It's hard to read, it almost looks like it's smudged, but that's the way the mark was done. The time frame on this is probably about 1915. It would have a retail price of, of about $3,000 to $4,000. It's not quite as much as it would be as if it was a 12-inch one. The value might be two or three times as you get larger.

GUEST: Thank you. And thank you, Uncle Harry. (laughs)
