Nice vintage single porcelain wall sconce.  The sconce is unmarked the manufacturer is unknown.   This sconce is in a ivory white with pink and blue floral patterns painted on the face.  It would look good and work well in a bathroom over a mirror. The wire, socket and lower 2-prong outlet are original.  The light does work as tested. The bottom 2-prong outlet is untested, as the wires are cut short.  The light has the lower pull chain with original porcelain end. The pull chain functions and has a good sounding click.  The porcelain is complete without any breaks or cracks. Does not include any mounting hardware.  Overall good, salvaged condition. Please be sure to look over all of the pictures as they are the best description. Feel free to ask questions when needed. Thanks for looking!
