This is a book of 1955-1960 Ford Product Service Letters.  The binder is actually labelled Ford Truck Selling Facts, but has been used for these letters.  The binder is soiled, but pages inside are good.  There is information on both Ford cars and trucks including Thunderbird, Falcon, Galaxie, Ranchero, F/C/B/P series trucks and more.  About half of the bulletins deal with 1959/1960 models with the remaining for 1955-1958 models.  See listing pictures for examples.  Will ship media mail.
