Wonderful pair of cast stone heavy bookends with incised carving mcm interpretation of horse figures on the front of each. 
Signed Kelsey- Luman P Kelsey of West Canton CT. 1906-1961.
Kelsey's mediums included pottery, wood and cast stone.
They weight over 6 pounds each and have a wonderful warm gray patina.
They are 5" tall, 6" across and 2.5" deep.
A little minor roughness on the corners but does not take away from the look and design!
