Older lampshade, white hobnail milk glass with ruffled top. Very nice pre-owned condition, with just the usual roughness at the bottom, no cracks or sizable chips, and nothing visible when in use. Measures approximately 8” at the bulge; top opening approximately 5-1/2” across (with about 3-1/2” opening), bottom opening a bit under 7”. A couple of tiny black “specks” in finish.
