Rare, incredible and extensive archive of early automotive and tractor engineering drawings, blueprints photographs, and related material from Raymond H. (even more than what is listed here is included). Four large drafting linens for tractor discs designed by Root for International Harvester, 1936 (largest 22 × 34 inches). Eight large blueprints, including two sets of plans for a bearing machine designed by Root for Shoemaker Automotive, Freeport, Illinois, 1925. Six blueprints with designs for International Harvester, 1930s; and twenty-four white prints and draft tracings for various designs by Root, 1930s (each 14.5 × 18 inches). Several loose graphite technical drawings. More than a dozen photographs related to engineering projects, including views of McCormick tractors and components; a set of twelve photo postcards of antique steam engine tractors, dated 1964. More than a dozen cyanotype photographs of tractor parts and agricultural equipment, 1930s. ++ Miscellaneous related ephemera. Some foxuing, staining, small areas of damage consistent with age, but overall this collection has been stored well over the years.
