This rare table lamp is definitely from Stilux because it had the label but it was lost. The seller guarantees the attribution to Stilux because he previously sold an identical lamp with the Stilux label. Attributed to Oscar Torlasco. Base in black stone. The sphere is made of brass-coloured metal. 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, European Plug (up to 250V).The wiring of this item may be original and might need replacement, if not specified otherwise.
