Adone Floor Lamp designed by C.P. & P.R. Associati and manufactured by Artemide, in the 1980s. We found the following in an Artemide catalogue: "Adjustable and articulated floor lamp in grey painted metal. Base in 'Pietra Serena', diffuser in plastic material." The Adone floor lamp is adjustable in height and position, for which purpose the three 'key-shaped' screws have to be used. 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.
