Set of 4 glass and brass wall lights - 1960s

Four ’glass and brass’ wall lights. Three pieces with two lamps and a single lamp. The lamps have a square shaped yellow copper base, a white lacquered metal arm and a "checkered" milk glass shades. All these lamps have a drawstring and can be attached directly to a wall socket. Good vintage condition; some lacquer damages at the white metal arm below the shades.
