Vintage cactus covered wagon lamp. The shade is made of lampshade parchment, hand-painted with a brush. 

The main parts of the wagon are made of Arizona Cholla cactus that has died and been dried by the sun and wind. 

It was made by Witmer Lamp & Shade Co. in Phoenix, Arizona.  It stands approximately 9 inches tall, measures 12 inches long, and measures 6 1/4 inches wide.

It has a hole in the top Wagon Shade and one wheel need refastened.   See PICS

In good shape, it would be at least twice to 3x as much.
