Vintage plafonnier, likely made in Sweden in the 1950s. It can be used both as a ceiling light or as a wall light, mounted either vertically or horizontally. The back part is plastic, possibly bakelite, with a beautifully patterned glass shade. It is made to be hardwired.

There is a chip in the glass as seen in the last picture, however, it is not visible when in use. There is some paint stains on the plastic mount.

Standard E26/E27 lamp socket.
