"Diabolo" ceiling lamp designed by Svend Aage Holm Sørensen. Produced by Holm Sørensen & Co in Denmark during the 1950s. Made from black and white lacquered aluminum and brass. Working both as up and down light. Very good vintage condition with few signs of age related wear and patina. Same model but made by ASEA. 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.
