Here is a set of four art glass shades of Bohemian origin. Although frequently referred to as Loetz, I have not found consensus if they were produced by Kralik, Rindskopf, or Pallme-Konig. The shades have a lemon yellow background color, with green white pulled feathers. They measure 4 3/4" across and stand 4" tall, with 2 1/4" fitter rims. There is an uneveness to the iridescence on these shades, along with nicks to the top and bottom edges. Good for use in a ceiling fixture or chandelier.
