Antique etched glass lampshade for a gaslight, or early electric light fixture. I love the allover chintz style floral on this piece.
This came out of the estate of a father and son business who worked putting electricity in many Wisconsin homes 1910 - 1940s. They saved many antique pieces, and then this collection remained stored away untouched for many, many years.
This measures about 3 1/2" deep overall, 6 1/4" across the rim of the open end, 2 3/16" across the fitter. It's in very good condition - no chips or cracks, just a little scratching.
