This painting is oil on plywood.  The dimensions are 14" wide (maximum) and 41" high (maximum). 

 

The wood is 1/2" thick plywood supported in back by a metal framework designed to prevent the wood from warping.  The edges of the plywood have been rounded and shaped.  The depth of the metal framework causes the painting to be approximately 1/2" away from the wall thus providing interesting shadows that change with lighting conditions.

 

There is "picture wire" in back of the painting and the painting hangs on the wall by the usual "nail-in-the-wall" method.

 

This painting weighs approximately 15 pounds.
