International Harvester began producing motor trucks in 1907. Early models included auto wagons, auto buggies and highwheelers. The company gradually expanded production to produce a wide variety of light, medium and heavy duty trucks. In 1961, International Harvester introduced the International Scout, a sport utility (SUV) type of passenger vehicle intended for a mass market. The McCormick-International Harvester Collection includes photographs and advertising literature documenting the development of International trucks.
