This is a fabulous creamy moonstone glass lampshade from Fenton. Fluted and ruffled with soft flowing hobnails, with a definite gorgeous brilliant opalescence to it, shaped like a fluted flower. There are no chips or cracks. It is 5" tall, approx 5.5" wide with a 2" fitter. This is thick glass which is a characteristic of Fenton, they do not scrimp on glass. I cannot find this lamp shade anywhere on the internet. Unique, most likely rare.
