Tiffany Style Slag Stained Glass Floral Shade Brass Lamp Base READ. Beautiful Tiffany style lamp shade and base.The lamp itself does not work. I've tried several bulbs but it does not come on. It may be the cord (there are no cuts or issue in the cord) or another simple fix. The shade is beautiful and in great condition. The measurement of the base of the lamp to the top of the shade is approximately.
