A unique lamp from the mid-twentieth century, manufactured by the German company Cosack Leuchten. The lampshade and base in classic black and a brass flexible frame, the whole looks elegant. The lamp in original very good condition. 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.
