A set of great wall lights marked Keuco, probably designed by Luigi Colani who created designs for Keuco Germany in the 1970s. The lamps are onion-shaped and made of Murano glass with "air bubbles" They are completely authentic, the glass is 100% flawless, the brass holders have minimal signs of use. Good and heavy quality and perfectly working, of course! This piece has an attribution mark, I am sure that it is completely authentic 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.
