According to 'US News', Calvin rates as one of the best National Liberal Arts Colleges in the USA. I can't really comment on that, but they do have an interesting collection of propaganda posters in their library.
If you are interested in German history, the collection of Nazi propaganda posters is fascinating:

They also have links to other collections.
The posters are part of a larger Calvin German history collection covering fascism and the Nazis, and post war East Germany.
