Rare pendant lamp design by achille and pier giacomo castiglioni in 1959. white methacrylate double shades with nickel plated brass finishes. original working wiring with 1 e27 lamp socket. the lamp is made up of 2 main lampshades: a small one consisting of 2 hemispheres that contains the bulb; and a larger hat resting on the structure. A small white methacrylate disc completes the design of the lamp in the upper part. overall very good condition: nickel plated oxidation as showed in the pictures. the height (cm 75) is determined by the electric cable so it is adjustable. 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, up to 250v (europe/uk standard).the wiring of this item may be original and might need replacement, if not specified otherwise.
