This is a Beautiful museum quality Tiffany Studios Reproduction Leaded Glass Purple Grape Vine lamp on the Bronze Tree Trunk Base. The lamp stands 30 inches tall on its 12 inch Bronze Tree Trunk Base. There are 710 pieces of glass in this lamp and the colorations in the Leaded Glass Shade are a rainbow of colors, striations, speckles, primarily Youghiogheny, Uroboros and Bullseye Glass. The leading of the glass is well done throughout the shade. The Shade is 18 inches in diameter and about 15 inches tall with its irregular upper and lower borders. The shade sits on a stub at the top of the Bronze Tree base. The Base is not an exact replica of the Tiffany Base, however, is real close with even more detailing and colors. There are 4 sockets on the base. The knob turns on one set of 2 lights, the other set of 2 lights or all 4 lights at the same time, then turns them all off. There is also an on/off switch in the power cord. Just a Wonderful looking Purple Grape Vine lamp for your home. I do have a matched pair of these lamps if you are looking for a pair of them.
