Lamp I.D.

Circa 1920's - 50's, marked PM & Co. Appears to be copper clad over base metal w/ hand done paint work.

 

I think you will need to show the whole lamp plus the plug and light socket at the very least to get help on this

 

Drew, it's always helpful to post a photograph of the entire object along with a close-up of the mark as context helps lead to identification.

Sorry, no sockets or wiring. stands 24" tall. The PM & Co. with copyright symbol shown the only marking.

 

Looks earlier rather than later. Style inspired by the Italian Baroque. The central figures are called caryatids.
