Beautyful! This brass, brutalist style wall lamp is designed by danish Svend Aage Holm-Sørensen in 1970s. This model is more rare than the flower model. The brass has been polished and therefore gives beautiful golden light. The inner circle can be adjusted in two steps so the light effect can be varied. (more direct/indirect) The lamp is fitted with a cord and plug, but of course can also be connected directly to a wall outlet if available. 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.
