Vintage glass ceiling light cover.

Guessing it to be from around mid century. Green glass with floral design embossed on inside. It has three holes for attaching. The dimensions as best I can figure are diameter 12 inches. Depth 3 inches. It has some tape residue on outside and two paint splotches, should be easy to remove. It did not work for the fixture I had hoped. But also looks good as decorative table top bowl.
