is a pair of matching Hobnail pattern white milk glass light or lamp shades.I am not sure of t age, but I believe them to be older. T is a letter (B) in a tiny circle at the base of one of them. The other has no marks that I can find. They measure approx, 5-1/2" tall, and are approx, 3-3/4" across the ruffly tops, the bases are approx, 1-5/8" at the outer edges.No cracks, but some roughness to the inner part of the bases, they are also not exactly round. Just a touch crooked.Email if you have any questions , Happy bidding and Thanks for looking!
