1962 GMC Truck 7 Common Profit Leaks Sales Brochure. This booklet is GMC's first public report of some of the findings of the Transportation Productivity Research Department. It cannot be called with accuracy a condensation of the Department's work; it foregoes technicality for readability, detail to brevity. It fulfills the purpose each time it stimulates top management to appraise the new-profit potential in greater productivity of fleet operations. Condition: 1962 written in the upper right-hand corner of cover. Some rust on staples. Some wrinkling from moisture damage on outside cover only.
