The museum has the largest collection of prehistoric Native American Artifacts in the State of Iowa on display.
Collections include artifacts from prehistoric Native Americans known as "Earth Lodge People" of the Glenwood Culture. Maps on the east wall identify known lodges for earth lodges in this region. Each red dot on the map indicates an earth lodge. Some of the artifacts of the Glenwood Culture collected include bone tools, bone fish hooks, and pottery. The displays represent many tribes, such as the Pottawattamie, Missouria, and Otoe and others which remain unknown.
The museum has several videos about the Pottawattamie Indians and the Earth Lodge/Glenwood Culture which can be shown on request.
From the Revolutionary War to the Gulf War, this room has many interesting artifacts to view. Uniforms from each era are dispayed, as well as items used by the soldiers. All branches of the services are represented. From insignia worn during the Civil War to a Purple Heart awarded during World War II, this room has many items used by soldiers from Mills County.
A unique collection of cameras can be found in the Phgotography room. Antique cameras on tripods, lenses and lighting equipment make this collection memorable.
Located in the Toy Room, you can see a windmill built of pencils, several farm scenes of antique cast iron toys, and several old doll buggies and their dolls. Shirley Temple paper dolls, a circus wagon and a cast iron train are all on display.
