Vintage hobnail pattern glass lamp shade with crimped ruffled top, beautiful amber glass. This is vintage Fenton, or another US glassmaker (L.E. Smith ?), we think.
The shade measures 7 1/2" in diameter, 7" across the fitter, and 5 1/2" tall overall. It's in very nice condition, some slight roughness to the fitter rim which is original from the manufacturing process.
