vintage peach luster iridescent glass lamp shades, ceiling fan light shade set

Set of four 1970s or 80s vintage peach luster glass shades for a light or ceiling fan light. These are all in excellent condition, it doesn't look as though they've ever been used.

The shades are about 4 1/4" deep, 5 1/4" across the crimped ruffle edge, 2 1/8" across the fitter rims. Color on all looks perfect.
