Cyclopedia of architecture, carpentry, and building : a general reference work
A multi-volume trade reference issued by the American Technical Society in Chicago in 1912 for builders, carpenters, and sheet-metal workers studying by correspondence. The plates are line diagrams: projection drawings of cornices and mouldings with numbered ordinates, dashed construction lines, and flattened patterns, offering designers ready-made geometric linework, lettered keys, and technical figure captions.
