The Corn Palace of Mitchell, South Dakota in 1905 with a swastika on the front. A Nazi Corn Palace? It does have a swastika on the front but the photo is from 1905. So it is a non-nazi swastika.
The Corn Palace is a building decorated with ears of corn all over the exterior. "WTF" you say? I was there once as a kid and that was my thoughts exactly.
