This elegant volume documents three hundred years of exquisite drawing tools, richly photographed and described, for architects, draftsmen, and engineers.Crafted in silver, ivory, steel, and brass, the instrument sets catalogued here range from small silver-mounted tortoiseshell pocket étuis to multitiered mahogany cases housing every professional aid imaginable. Computers have supplanted their manufacture and use, yet these exquisite traditional instruments are still fully functional. 225 color photographs
