I was in South Dakota recently and passed by something called the Corn Palace, in Mitchell SD. It's a building used for an annual agriculture exhibition, and sometime around 1900 they decided to annually decorate the outside using nothing but corn of varying colors. It's a pretty cool place, but in the exhibition hall, there's an image of the Corn Palace decoration in 1903, and prominently placed all over the building are these huge swastikas -- which were also Native symbols of fertility (I think -- maybe just good fortune). The curator had to post this huge notice that said, 'Look, this is a photo from 1903. This has nothing to do with Nazis. We're not Aryan supremists.' Real shame when things get taken that way.
