ANTIQUE Lighting & sconces

Circa 1915-30.   Very fine quality Art Deco desk lamp.  Elegant design and sumptuous materials make this table lamp a standout. Heavy solid cast brass, mounted on a thick , finely veined marble base, finished with a strikingly colored Art Glass shade making this fine light a handsome addition to any decor. The still shiny brass has a lovely, mellow, original patina. The shade is the color it appears in the photos when unlit and much redder when lit.  All very good original condition, the brass arm has an ever so slight wave to it that we have pictured in the next to last photo.  We will re-wire using antique style covered cord.   Stamped on the key with a mark that looks "Arts & Crafts" that I do not recognize.  14 " tall x 10" deep x 7" wide.  The shade is 7" diameter x 3 3/4" high.  Price $650.
