Let me start by saying that I do no know much about this lamp but I am willing to try to answer any questions. Now what I do know. This lamp was found in the attic of an 100+ yr old house in baltimore and does currently work but will probably need to be rewired. I believe that this is a weber 1920s or 30s Era art nouveau of brass or possibly cast iron. It is a reverse painted glass of a forest next to a river. It is about 2ft tall and 2ft wide with the shade on and about 15lbs and it is dual bulb and possibly 1 bulb in the base. One of the sockets will need to be soldered back on. If you think you know more about this and are possibly interested please feel free to contact me. I am also open to offers so feel free to reach out.
