old deco ceiling light fixture w/glass shade, vintage lighting

Old 1920s or 1930 deco vintage ceiling light fixture with a glass shade. The glass shade is about 16" across and is an ivory color. The fixture is 6 1/4" across where it fits to the ceiling and holds three light bulbs. There is some roughness to the edges of the shade and some chips around the center hole that don't show when the shade is in place. There is also some wear and minor flaking to the brass plating on the fixture.
