set of two early 20th century american vintage industrial "pittsburgh" interior store window display reflectors with original green enameled finish largely intact. the fluted shades are treated with a reflecting element (i.e., silver nitrate) sandwiched or encased within the glass. 300-500 watt bulbs were likely used to produce an angled "flood of light." fabricated by the pittsburgh reflector & illuminating co., pittsburgh, pa. priced for the pair.
