Last summer we went to the Library of Congress in D.C. I didn't know what to expect, but I really enjoyed it. Duh, me, books, written word, history of writing in America, kind of makes sense! In addition, I found some really great art in the gift shop. We just painted the upstairs hallway, and I've slated these three prints for one of the walls. I think they were from series of postcards or posters, not sure on the history.
