Here is a set of four antique art glass lamp shades produced by Kralik in the early 1900s. These shades feature red threading on an iridescent white background. They stand 4 1/4" tall, measure 5 1/4" across, and have 2 1/2" fitter rims. The threading is in good condition on all of the shades. One has a tiny nick on the outer edge, two have minor fitter rim roughness. Ideal for use in a chandelier or a pair of wall sconces!
