The Painter, gilder and varnisher's companion : containing rules and regulations in every thing relating to the arts of painting, gilding and glass-staining ..
A Philadelphia trade manual from 1869 by Baird, aimed at house painters, gilders and varnishers, collecting rules and recipes for painting, gilding and glass-staining. Its pictures are plain line diagrams of apparatus: cross-sections of a furnace-like structure, a mechanical linkage over a cylindrical vessel, and a sealed chamber with pipes. A designer might borrow their clean technical line style and the look of old engineering schematics.
