Vintage 1950s round white glass ceiling mount light fixture, with concentric circles.

8" diameter x 4" tall. The inner rim where it would touch the ceiling is 7 7/8" diameter.

Weighs 2 lb 5 oz unboxed.

In good vintage preowned condition, not chipped or cracked; there is a tiny nick on one of the ribbed rings; there is some discoloration and a bit of the white finish rubbed off, on one part of the edge which would be near the ceiling and not visible when mounted. (see picture 9). I believe it is from storage, perhaps rubbing against something? The only other thing I see is some rusty marks from where it was mounted, again, not visible when mounted.

Please see pictures and let me know if you have questions.
I will pack carefully and usually ship on the next day after payment is received.
Thank you for looking!
