Here is a pair of art deco wall sconces that came out of an old house in Pittsburgh. I am not sure what the metal base is - possibly chrome or heavy aluminum. The Union label is half worn off on the underside of the base and there is no manufacturer name, but these lamps were most probably made by the Lincoln Lamp company in the 1920’s. The glass shells are frosted - very unique. There are no chips or cracks on them. They’re 100 years old and still in nice condition. There are only a few paint spots from previous owners having painted their walls. Also the bases are in need of a good cleaning and painting, and it’s probably a good idea to rewire them also. They can be used in the home ( great foyer pieces) or out on the porch for the early century look.
