Here is a gold iridescent art glass shade produced by Quezal in the early 1900's. The body is ribbed, and is slightly larger than most of these shades. It measures 6 1/4" across and stands 5 3/4" tall. It is unsigned, but was produced by Quezal (not the colors/iridescence you find in Steuben examples). There is chipping to one side of the fitter rim. There are no other noted damages or repairs to this piece. Great to use in a desk lamp!
