Hanging ceiling lamp. Very pretty design but there will be some work to do. I think someone tried to create a hanging lamp that would plug into the wall. The electrical cord goes from the lamp, in & out of the chain, into the Canopy and out the other end to the wall outlet. You cannot attach the canopy and have it flush against the ceiling.
From the shade to the canopy is about 23", from the canopy to the end of the cord is 42". The canopy is 4.5" across. The shade is 7" deep and 8.5" across at the widest end.
Canopy has some marks on it.
