One of three large shell shaped glass sconces by Rupert Nikoll, Austria, manufactured in Mid-Century, circa 1950 (late 1950s or early 1960s).An organic shaped glass piece is mounted with brass bolts on a white painted metal backplate.The textured glass structure creates a fantastic light and is similar to the lights of Kalmar from that time period. Each lamp takes one medium or standard screw base bulb. The lamps are professionally cleaned, newly wired and ready for use.It is possible to install this fixture in all countries (US, UK, Europe, Asia, Canada,) although it may be necessary to purchase different light bulbs suitable to local electricity. The price is per light. They are sold individually, as pair, or as set of three items.
