Antique Marble Lamp - $40 (Baldwin)

Vintage lamp 1950s.
Shade is brittle, might be original.
The other hardware looks original.
Newer plug was added to the end of the old cord but I have a vintage cord from some other old lamp in good condition which can easily be added.
Socket works but missing the thumbscrew.
Marble has one small chip.
I plan to do the work of adding new cord and replacing socket myself in the near future and take better photos but know that when happens the price will go up.
Lamp came from an estate in Port Washington NY.
