Vintage 1950 Diffuser for Ceiling Light

Rare find! This lovely piece was installed in our Circa 1929 house when we bought it in 1991. Frosted glass with floral motif in clear glass. 7-1/2” Dia x roughly 4” High. The opening at the base, where it attaches to the light fixture, is 5-5/8” in diameter. It was designed to diffuse harsh light from a lightbulb in a flush mount ceiling fixture. Beautiful piece in perfect condition.
