These are all children's puzzles. The Bear & Leopard puzzles were
egg washed, probably from the late 19th century. The Owl & Monkey puzzle is
as I received it, in a picture frame. I believe that it was one of a set of
three puzzles produced about 1910. The Animal Picture Puzzles (set of 3) and
the Dissected Animals (set of 6) were probably produced in the late 1930s or
early 1940s.
