These are a vintage pair of cast metal salt and pepper shakers.   These are souvenirs of the Corn Palace located in Mitchell, South Dakota, and are replicas of the building.  Shakers measure 1-1/2" x 1-3/4" x 1-1/4" in height.  These are not maker or country of origin marked. I would guess from the 1930s or early 40s and made in Japan.  Set is in very good used condition.
