RARE Quezal Flower Blossom Art Glass Shade produced by the Quezal Glass & Decorating Company of Brooklyn, NY. . This is the fourth example of this shade I have had in over 50 years of collecting and selling fine art glass shades. The first three I found in Switzerland. These might have been made for the European market where some of the light sockets retain their shades by use of a screw on ring which goes on the inside of the shade. It is in MINT condition and is 3 1/8 Inches in height.
