Barreled sunlight for industrial plants.
A 1924 trade booklet titled Barreled sunlight for industrial plants, issued by the U.S. Gutta Percha Paint Co. to promote its white reflective coatings to factory and plant owners. The pictures are mostly photographs of bright, whitewashed interiors of factories, creameries, bottling plants and bakeries, with one engraved perspective of a long hall; a designer might take from them the use of pale, light-reflecting surfaces and rows of machinery receding through open space.
