Vintage Silk Lampshade Boudoir For Sale

From ChatGPT

I did find specialist examples of petite boudoir lamps using silk, antique French metallic lace, ribbonwork and small shades associated with the 1920s. One documented example has a shade only 4½ inches in one dimension, remarkably close to yours.

So I’m increasingly comfortable describing yours as a handmade silk boudoir lampshade, probably circa 1920s, decorated with metallic lace and applied period-costume portrait medallions. I would leave the country of origin as unknown, possibly French or French-inspired, unless we uncover stronger evidence.
