In 1919, Joseph B., Robert C., and Ray A. Graham began producing kits to convert Ford Model Ts into trucks, and by 1922, they expanded to Detroit and Stockton to open plants for Graham Brothers truck brand. In 1925, the Dodge Brothers bought Graham Brothers truck firm and the brothers took on executive positions at Dodge. In 1927, the brothers entered the automobile business and purchased Paige-Detroit Motor Company, makers of Paige and Jewett automobiles. They established the Graham-Paige company and produced their line of Graham-Paige cars with six- and eight-cylinder engines. Graham-Paige made most of their own bodies and engines and developed several innovative features, such as enclosed fenders and a banjo frame. The company also produced a crankshaft-driven supercharger in 1934. Despite initial success, sales fell during the depression, and by 1935, Graham signed an agreement with REO Motor Car Company to purchase car bodies. Graham-Paige's logo featured profiles of the three Graham brothers and was used in insignia on the cars.
