Depression Era Blue Hobnail Ribbed Glass Ceiling Shade

This is a really beautiful vintage depression ere glass either ceiling or lamp shade with hobnail and ribbed banding. It is very nice heavy pressed glass and the light blue looks like it is enameled on and is in great condition. The only damage is a bit of chipping around the center hole, but it doesn't go all the way through. Look at the picture carefully. It measures 10 and 7/8 inches across and 3.25 inches high. This is a lovely piece and would add wonderful accents to any room.
