The Kiggins Theatre, Vancouver, WA. Opened in 1936. It's original art deco marquee (just the lower part) was replaced with a more moderne looking one. I don't know why it was changed. The theatre was recently restored and reopened.
One of the most beautiful examples of Art Deco still remaining, the Paramount Theatre stands as a gem among stones of Oakland, CA. Opened in 1931, the lower part of the marquee has undergone a few facelifts over the years. Of of my favorite theaters to stand before and look at. Just make sure you don't go to downtown Oakland at night by yourself.
