This very well-preserved circular lamp made of brass can be installed both as a wall and ceiling light. The lower cover is a matt etched gala disc, which is fixed by a screw -on brass end. The side edge forms a time -typical perforated sheet with a plastic panel inside. This piece is attributed to the mentioned designer/maker. It has no attribution mark and no official proof of authenticity, however it is well documented in design history. I take full responsibility for any authenticity issues arising from misattribution, Up to 250V (Europe/UK Standard).The wiring of this item may be original and might need replacement, if not specified otherwise.
