ART DECO LAMP

-We bought this at a yard sale in Walton, KY in the summer of 2010
-It is made of wood and some kind of metal, possibly brass...it is not pitted
-It stands approx 24" tall and at it's widest part, measures approx 21"
-The base measures approx 12" x 7"
-The wooden parts of the lamp were painted black, but as you can tell, some of the paint is beginning to peel off.
-We would like to know who made this lamp, and what era it belongs to

Thanks for any help you can give us, D and M Miller
