This is an awesome Thick Glass Art Deco Square Ribbed Light Fixture Shade. I've never seen a shade where the light bulb opening is on the side. It measures 9 3/4" X 9 3/4" X 6". It's in excellent condition, I can't find one flaw. It's a heavy piece as it weighs just over 5 pounds. I have a larger shade just like this one for sale and would be happy to combine shipping.
