Members of the American Truck Historical Society (ATHS) brought a wide assortment of classic rigs to the 2016 Mid America Trucking Show, illustrating almost every era of U.S. truck design and development - from a weathered 1929 International SF 46 to a pristine 1987 Peterbilt Model 359 along with a little bit of everything in between.
