This desk lamp is the A4 model designed by French designer Alain Richard in 1958 for the manufacturer Disderot. It consists of a Carrara marble disc to which a vertical chrome-plated metal stem is attached. A black lacquered aluminum reflector completes the design; it slides along the stem, allowing the height of the light to be adjusted. This lamp will perfectly adorn a desk top; we love its materials, which add a chic and refined touch to the overall effect. Its sleek design and timeless colors allow it to easily blend into any decor style. 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.
