Question About the Birdhouse in Your Soul MV

I'm designing a Halloween costume of the people in the BHiYS music video. (The people with the placards and glasses with William Allen White's eyes). I can't figure out what the font that is used on the back of the placards, that reads "STOP ROCK VIDEO". I believe it's Arial Narrow, but if anyone sees a different one, please let me know.
