This ashtray is my one and only piece of Phoenix Glass - and what a wonderful item it is! This is the #263 Phlox pattern ashtray in the Sculptured Crystal treatment. (crystal glass with a blue ceramic wash applied.) The ashtray is the 5 1/2 inch size - the larger and much harder to find of the two sizes that were made in this pattern. Produced in 1938, it's a rare find indeed! Excellent condition.
