The Pix Theatre, Woodburn, OR. I am guessing this theater opened in the 1940's, but I can find nothing certain on it. It was recently used as a furniture store, but it's now just a rotting eye sore.
The Academy Theatre, Portland, OR, with Mt. Hood looming the the background. Opened in 1948.
The Fremont Theatre, San Luis Obispo, CA. Opened in 1940.
