old hand-painted glass drop ceiling fixture light w/ fan collar lamp shade

1950s vintage glass shaded ceiling fixture light (this is made to mount flush to the ceiling, we just have it hanging to show the unusual shape more clearly in the photo). The glass is two separate pieces - a handpainted floral shade under a collar of glass which fans out above it.

This measures 11 1/2" in diameter overall, and about 7" long from the ceiling. It holds one standard size light bulb. The metal fixture with the electrical wiring and the two-piece shade are all in very nice condition.
