Pair of vintage "Clair-Obscur" wall lights by RAAK, 1960s

For sale a fabulous pair of "Clair-Obscur" (model F-32270) wall lights sconces by Dutch lighting creator RAAK Amsterdam, dating from the 1960s. The lights are in working order and in good vintage condition, with marks and scratches commensurate with 50+ years of age & use but nothing to overly detract (please see photos for the worst of it). Both lights still retain their original Raak Amsterdam stickers on their mounting plates.
