This very cool modern style desk lamp is attributed to Robert Sonneman. From @ 1980's. Black textured metal with brass columns and chrome trim at the top of the columns. The thick glass shade has a green tent that is more noticeable when lit. On/off dimmer switch on the base. It measures 15" H X 17 1/2" L X 4 1/2" D. It takes a max 100 watt type J bulb. I installed a new bulb and will send with an extra. The glass panel under the shade need to be removed to install a new bulb. It has 2 Philips head screws. Both have surface rust. It's in good working condition but has several cosmetic issues. The brass columns are scratched up, not too noticeable unless you very close. The thick glass shade has small surfaces scratches along the outer edge in a few spots. The on/off switch is tarnished. It was very dusty when found and I did my best to clean it but may need more detailing.
