Original Cadillac (Service) Shop Manual Supplement for 1951.  Covering Cadillac 51-61, 62, 60S, 75, and 86 Commercial Cars.  It has updates and any new information or procedures pertaining to the 1951 Models and was meant to be used with the 1950 Shop Manual [not included] for full coverage. Covers: body, frame, suspension, brakes, engine, clutch, transmission, fuel, exhaust, steering, wheels/tires, chassis, electrical, radiator, lubrication, etc.  It is in fair condition. It has been damp and shows some wear, soiling and blemishing [see photos]. The staples have rusted away, so the cover and staples have rusted away. Very rare and informative piece of automotive history.
