The Cinema Treasures website says: "The Rapids Theatre opened on February 28, 1950. Designed by architect Talmage C. Hughs, with Albert S. Johnson as theatre consultant. The façade is finished in a porcelain enamel. Inside the auditorium, seating was provided in orchestra and balcony levels, and there was a cry room at the rear left hand side of the balcony. The decorative treatment comprised of free hand drawings on the side walls and front of the balcony which consisted of curves and swirls."
This is one of a couple instances in which I've read that my grandfather served as a "theatre consultant" while also being the general contractor. Some of the "free hand drawings" mentioned in the article can be seen in two of my grandfather's 1950 interior images below.
The six color 35 mm slides that I've posted below were taken by Al Johnson in 1950. They include four images of the entrance at different times, and two of the interior. The building is no longer in use as a theater.
