Paints, varnishes and brushes; their history manufacture and use
This 1923 trade manual was produced by the Pittsburgh Plate Glass Co. as a publisher-authored guide to paints, varnishes and brushes, covering their history, manufacture and use for painters and the building trade. The pictures are plain black-and-white photographs of factory machinery, paint tins carrying the Pittsburgh brand, and a single steel painter's putty knife on a neutral ground, offering a designer documentary views of early twentieth-century industrial production and tools.
