Great action scene cut by unknown maker. Plywood, interlocking. Unfortunately, maker's blade was not perfectly perpendicular when he/she cut the puzzle resulting in a tight fit and some pieces fitting in from only one direction. One of our viewers has identified the artist as R. Farrington Elwell, (1874 - 1962). Born near Boston, Massachusetts, he became one of the better-known late 19th and early 20th Century illustrators, painters and sculptors of western subjects and was noted for his portrayal of bears and horses standing on their hind legs.
