This is a perfect piece of hand blown signed Quezal Art Glass produced in the US, as a competitor to Tiffany, and was sold at around the same price point. The glass is iridescent, this piece is mint. It measures 7 1/4 inches tall and 2 1/2 inches across the widest part of the base, which is stamped with a Q variation mark and signed Melba.. Another collector commented that this was designed for Melba Glass Co. and that it was designed as a perfume with a stopper, I do not notice any scratches at the opening, but if it was originally a perfume, the lid is gone! The piece is free of any chips or cracks. Quesal was produced between 1902-1924.
