Speedwell Motor Car Co. Radiator Emblem

This radiator emblem belonged to a Speedwell automobile that was manufactured by the Speedwell Motor Car Company of Dayton, Ohio from 1907 until 1914. The company advertised their vehicles as “a car no man has ever worn out.” The Speedwell sold from between $2,500 to $3,500 in a variety of body styles. This green emblem has a large stylized “S” in the center with the cursive text “Speedwell” diagonally across the emblem in gold.
Radiator emblems are small, colorful metal plates bearing an automobile manufacturer's name or logo that attached to the radiators grilles of early automobiles. Varying in shape and size, the emblems served as a small branding device, sometimes indicating the type of engine, place of manufacturing, or using an iconic image or catchy slogan to advertise their cars make and model. This emblem is part of the collection that was donated by Hubert G. Larson in 1964.
