I have been waiting a while to find one of these. It is the Rougier tube lamp in the ball style as a wall sconce. I previously posted about the Rougier tube lamp sconce as being part of the décor of Cliff Barnes’ and Afton Cooper’s house in Dallas.

The lamp measures approximately 17” in diameter by 9” depth. Be prepared to open your wallet for this one, though. eBay item 251234091786, Buy it Now or Best Offer (United States).
