All these sets below nicely display their original foil label which dates this series to the 1950s when Enesco imported them from Japan.  The sets depict various nationalities, albeit it appears American children are represented twice.  The sets are nice and small - 3'' in height.  To our knowledge, and supported by Irene Thornburg's research from her "Big Book" of salt and pepper shakers series on page 116, this appears to be a complete group.
