Robert Sonneman Amazing Space Age Brass Chandelier With 9 Lights

Circa 1970's
Amazing Space Age brass chandelier with smoked glass panels with 9 light bulbs for an enormous amount of light.
The chandelier has a large chain so it can be hanged at a tall space.
The lamp is in good working order, the brass has a nice aged patina and only a few scratches which is to expect in vintage pieces.
