This Goethe lamp is attributed to Bünte & Remmler and was designed by Christian Dell. The arm can be swiveled 180° and the shade can be tilted to cover a large area for direct lighting. The aluminum shade retains the original black paint on the outside and silver paint on the inside. The polished lamp arm is also made of aluminum and the handle is painted black. The lamp is stable due to the heavy cast-iron foot and equipped with an E27 socket. I have official proof of authenticity such as vintage catalogs, designer records, or other literature sources and take full responsibility for any authenticity issues arising from misattribution, European Plug (up to 250V).The wiring of this item may be original and might need replacement, if not specified otherwise.
