Reports
A 1908 technical report issued by the Scientific Section of the Paint Manufacturers' Association of the United States, published in Philadelphia for paint makers and testers studying paint performance and corrosion. Its pictures are plain photographs of test panels, weathered boards and a microscope-style field, with no decoration, so a designer might borrow their raw texture: mottled grey surfaces, hail-pitting, dark blotches on pale ground, and the flat documentary look of laboratory evidence.
