I have a Craftsman style building, built about 1919 or 1920. It has some metal shutters that I want to know more about. Some of the building changes were made about 1930, if that is helpful. The label says "Outside Venetian Blind Co., Dallas, Texas, Ft. Lauderdale, Fla" and the style of my shutters/blinds are "Clearview Gay Room." They were originally a light green color. Does anyone know anything about these?
