This Kaiser Idell Table Lamp is a fine example of Bauhaus design, originating from the 1940s. This model is the nr 6631, which has a curving arm supporting an adjustable mushroom-cap shade.
It was designed by Christian Dell, a Master silversmith, who was Bauhaus’ metal workshop master from 1922 to 1925.
