The Arlene Schnitzer Concert Hall, Portland, OR. Opened as the Portland Publix Theatre in 1928 and soon renamed to the Paramount. It's sister theater is in Seattle. The vertical sign is a 30 year old replica made to look like the original. This theater often appeared on one of my favorite TV shows, Leverage.
The Roseway Theater, Portland, OR. Opened in 1925. This theater has undergone a few facelifts. Every few decades, they change the design of the rose and the signage.
The Avalon Theatre, Portland, OR. I have some conflicting information about this theater...I have heard that it may have been built in 1913 as the Sunnyside Theatre, which would make sense if you looked at the building and understood the construction of the day. However, the sign in the photo says "A Portland Tradition Since 1925." It could be that it became the Avalon in '25, or that could be when it was built. For now, that will have to remain a mystery.
