Circa 1905. Pair of large handsome, Arts and Crafts green slag glass hanging lights with provenance from the Frick mansion in Massachusetts. These unusual shades are fine cast bronze with their original patina. The shades are a brilliant emerald green glass with swirls of white and are lined in pure white glass. The green outer glass is in excellent condition. The interior white glass has a crack on one shade and two cracked panels and one chip on the second. The damage on the white glass is only visible when viewed from underneath. Each shade has four original brass sockets which have been re- wired for safety. 20 " long x 18" diameter, without chain. Can be any length. Price $ 8000 for the pair.
