Mid-century wall lamp by Cosack with a striking Diabolo shade. Better known in the table lamp version with a “crow’s foot”. Here in a very rare version as a wall light. A sober design with elegant shapes. The striking element of this lamp is the large Diabolo shade with its soft curves. The shade is connected to the wall base via a simple brass shaft. The quality of the coloring is special. The base and shade are finished with a creamy white textured lacquer. In contrast to this is the smooth brass surface of the shaft. The light has a pull switch. This and similar designs are often attributed to Louis Kalff. But there are no sources for this. Furthermore, Kalff never worked for Cosack. The lamp is in very good condition with signs of wear and patina. 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, Up to 250V (Europe/UK Standard).The wiring of this item may be original and might need replacement, if not specified otherwise.
