Lamp Made in Italy

Your lamp appears to be a Capodimonte style lamp, most likely from the 1920-1940 period. Most Capodimonte pieces are highly decorated in floral and other kinds of molded porcelain in high relief. The one pictured doesn't seem to have molded flowers, but does have intentional cutouts where the flower's petals would be. The base, which is bright and lovely, appears to be in good condition, as does the lamp overall. It's my best estimate that your lamp may be worth $60-$75, more than likely imported and sold through department stores in the early to mid part of the last century. It's a lovely object and a family piece which should be treasured for those values alone.
