The Kister Building is the location of the Society’s main office. It houses a formal gallery with a permanent exhibit and a rotating exhibit. The permanent exhibit contains displays of agricultural implements, an extensive military collection, American Indian artifacts, pioneer-era tools and an unusual wood-carving collection, which includes a working ferris wheel. Another display, popular with school children, features small, taxidermy animals from the 1904 St. Louis World’s Fair/Louisiana Purchase Exposition.
