Postmodern Memphis style wall lamp, designed by Ettore Sottsass in the 1980s. Sottsass founded the iconic Memphis Group in 1980 and made a series of lamps called Stoja as a guest designer for IKEA Netherlands. The lamp is made out of wood and metal, and is turned on by pulling the yellow ball. The plastic grille that would sit behind the blur triangle is missing. There is some wear to the paint. Apart from that it is in good condition.
