The Ox Cart

This is an original oil on canvas painting of an Ox and Cart coming down the road.  The painting has 3 intials lower right, they seem to read: "W. ?. S."  Weve been unable to make out who the artist was. We feel the painting is from the late 1890's and is most likely American in origin.  The painting was expertly done.  The canvas laid on board measures 19X13 inches and is in a 19th century gilt frame.
