It has elements of Arts and Crafts, Art Deco and Art Nouveau movements. Thereby placing it approximately in the 1910's.The top portion of the shade is green slag that ranges from dark kelly green to light mint. The bottom portion is shades of turquoise and sky blue. The over lay appears to be copper (non magnetic) The rest of the metal is painted a coppery shade. It does work but I would recommend rewiring it.
Overall it is in very good condition. There is a hairline in one panel of the green glass but is it stable. One tree top is missing on one overlay.
Typical wear on the metal. Please ask any questions you may have.It is very beautiful when lit! 19" tall and the shade is 12" x 12. PLEASE VIEW ALL PHOTO'S FOR A FULL VISUAL DESCRIPTION.
