Riddell specialized in cast aluminum lighting during the 1930s. In particular their art deco lights are prime examples of style and time in which they were made. This sconce is per Riddell cast aluminumwith some gold highlights. The aluminum has a nice oxidized patina that highlights the casting details. The wiring is new and so are the socket insulators and the antiqued candle covers. Marked Riddell on the back plate. The switch is original and works, but has been disabled as it won't be needed when the sconce is hardwired to a wall switch.
