Robert Sonneman Black Chrome Floor Lamp. Made in the 1970s, an outstanding design by Sonneman; the impressive 14" deep vented conical shade is beautifully supported by two chromed uprights and an aluminum collar. Below the shade is the light source, a chrome cylinder (holding the bulb) with a three-way switch at the bottom, supported by two chromed rectangular blocks. The lamp is supported by a powder coated bent metal plate, open on the ends. In excellent original condition, it measures 14" X 58".
