A wonderful high-end light with thick marbled blown glass. Manufactured in the 1960s. The glass of the light fixtures is made of white and smoked glass and is giving the piece a playful appearance which refracts the light, filling a room with a soft, warm glow. The fixture requires 1 e27 light bulb. Dimensions: diameter: 11.81" (30 cm) depth: 4.72" (12 cm) cleaned and well-wired, in full working order and ready to use. The frame is in very good condition. Hillebrand is a manufacturer of high-end fixtures. The companies show an excellent quality. 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.
