Jumo Model GS1! This art deco desk lamp was made in France by Jumo. It is made from lacquered metal and features two joints to adjust the lamp. The big lamp shade and the long arm make it possible to lighten a big area. 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.
