There is a Swedish-American museum in Chicago, they sometimes display things like that. You might find a Norwegian museum near you?
Related, I really don't care for much 'modern art', or 'performance art', but there was this weird display of postcards at the Art Institute a few years back. It was just the back of the picture postcards and photos with messages on the back. It was oddly fascinating, as you read the message, and then just imagined what the people in the picture were doing. Not sure I consider it art, but it was kind of quirky fun.
I think little bits of history like this are interesting. They provide a different insight from facts and figures, just little bits of daily life.
