used in a theater in Detroit. Joe Maurath sent me this pic, I figure it deserves a place of honor in the vintage photos album. Vintage photo, it is, at 54 years.

This system would have been all tubes, transistors were still in their infancy, and were just starting to find use in portable AM radios, and some very early computer logic modules.
