One of many firsts at the Indianapolis 500, occurred on the first post-war running of the race. Louis Tomei in his Boxar Tool special, used a radio in the race to communicate with his pit crew. The car was entered by Joseph Hosso and featured a Stevens chassis with a Brisco six which drove the front wheels.
Evidently the Raytheon Company undertook setting this all up with a radio station in the box truck behind the two cars. This is a staged photo before the race and interestingly Emil Andres in his 8CTF Maserati also appears to be wearing a set of earphones and a mouth piece as Tomei is. The antenna is clearly visible on the tail of the Boxar Tool Special. Unfortunately the radio was not put to a full test, as Tomei went out on the 34th lap finishing in the 26th position. Andres faired much better by bringing his car home to finish in the forth position.
