Floor lamp by Sergio Mazza, produced by Artemide in the 1960s. Fantastic mid-century design. The base is made of black veined marble, the stem is metal, and the diffuser is made of white striped opal glass. 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.
