As mentioned last time, the Rendezvous Theater's Jewel Box Theater used to be a screening room where movie distributors would promote their latest offerings to theater operators. The room itself was a miniature movie theater; the display showroom for a theater-design company operating in the same building. During the so-called Golden Age of Hollywood, firms such as this would build and completely equip a movie house wherever you wanted one built, based on a complete prototype plan. Today's strip-mall multiplexes are also often built from prototype plans -- just much less beautiful plans.
