A fantastic example of machine age art deco design. Vintage 1930's -to early 1940's. Construction and materials look a lot like Kurt Versen, Gilbert Rohde or Chase but there are no marks just an illegible label on the socket. The lamp has a pull chain on/off switch with built in pen holder and two recessed squares for change and paperclips.The shade swivels on a ball and socket joint. Nice chrome finish with black enamel trim on the shade and base. Overall condition is excellent for the age showing light signs of abrasive wear and patina. Has a few touched up spots in the black finish. No dents or dings. See pictures for further description.
