Huge 1930s vintage deco moderne light shade for industrial or commercial setting lighting, antique architectural salvage, a genuine original, not a reproduction.
This cone shape measures 7" deep, and the shade measures 20" across the rim and opening. The old mounting handware is still in place, as shown.
We haven't been able to find a maker's mark on this at all, sorry! It's in excellent condition, minimal rust to the hardware, no chips or cracks to the heavy glass of the shade.
