Matson & Mechanic at Indiana Trophy

You won't find a lot written about Joe Matson on the Web but he was an auto racing driver of some prominence in the early days of the sport in America. Matson competed in the 1912 Indianapolis 500 and the Vanderbilt Cup twice. His biggest success appears to have been his triumph in the Indiana Trophy race which was held only once,  on June 18, 1909, as the support race to the June 19 Cobe Trophy.
 
This is an image artifact of a photo (published in the June 19, 1909, Indianapolis Star) of Matson and his unidentified riding mechanic in their Chalmers-Detroit racer before their victory in the  Indiana Trophy on a public roads circuit through and around the Indiana cities of Crown Point and Lowell as well as a lot of countryside in the northwest corner of the state near Chicago. Check out another photo of the two men that was published in the June 19, 1909 edition of the Indianapolis News. The paper reported that Matson was of Danish descent and that he had only recently graduated from being a riding mechanic to assuming the driving duties. The paper also described him as "sturdy and phlegmatic." Other sources indicate the mechanic's name was Frank Vaughn.
