Race car driver Townsend Bell was noted for wearing a Robert Graham polka dotted fedora at the 2013 Indianapolis 500. For the 2014 race, Bell brought the company on as a primary sponsor of his KV Racing Technology Number 6 car. Both the exterior and, unusually, the interior of the car display characteristic colors, patterns, and logos. Bell's racing crew uniforms and firesuit were likewise custom designs. Robert Graham also sponsored Bell's subsequent Number 24 and Number 29 cars, which raced in the 2015 and 2016 Indianapolis 500s, respectively. According to Stock, the company has an interest in motorsports predating sponsorship of Bell, due to a noted overlap in customers and a suggestion by Bill Sweedler, a race car driver and financial manager whose firm, Tengram Capital Partners, owns a majority interest in the company.
