Vintage frosted white lamp shade.  Fan pattern.  Replacement shade.

2 1/4" fitter.  4 1/8" tall x 4 1/2" diameter across the bottom.

Measurements are approximate.

Good condition.  Has some roughness along the fitter.  Last pic shows what appears to be a small chip and a small cracks on one of the fan designs.
