The lead and zinc pigments
A 1909 technical monograph by Clifford Dyer Holley, published in New York by J. Wiley & Sons, on lead and zinc pigments and their manufacture for industrial chemists and paint makers. The four plates are black-and-white photographs of plant interiors: wooden troughs and walkways, machinery with belts and piping, a worker in a shed, and an exterior view of a works with a rough yard. A designer might take their stark industrial geometry, diagonal beams and repeated vertical channels as raw material for utilitarian layouts.
