This listing is for a vintage Art Deco porcelain wall mount sconce with an electrical outlet on the bottom.  It measures 3 7/8" x 6 1/8"... with a 3/8" hole.  The light has the nice Deco ribbed lines.  The light needs rewired.  There is no mounting hardware with this.  There are, what looks to be, a couple of small manufacturing flaws and spots on this piece...still looks nice.   The chain pulls down fine, but sticks.  A good cleaning and lubrication might do the job... or can be replaced when rewiring.    This is a nice Deco light from a nice estate.   Thanks for looking!
