This is a Fenton Glass white opalescent lamp fixture globe or shade. I do not know the pattern name or the manufacture date. I could not find any information on it. It is marked, “Fenton”.
I have three (3) of these globes for sale, each one separately. They are all three in excellent condition.
Each one is 4-1/2″ in diameter at the largest end. The smaller end is 2″ outside diameter, and 1-1/2″ inside diameter. (These are approximate diameters. Please look at the pictures for your verification.)
If you have any questions, please e-mail.
