I have no prizes, for I am po', but I can congratulate those who get it right in the comments. :)
Edit: A little hint. The Museum's name is something like (no, I can't read it in that picture either, sorry, I was shooting the picture out of the window of my car while driving), "Something Museum of American Art", so the reference to patriotism in and of itself doesn't offend me. I mean, I think it's a cheap shot for playing on current sentiments, but hey, that's business. No, it's the picture they chose to represent this...
