From 1982 to 1988 Piedmont Airlines, apparently feeling flush in good times and with an infusion of cash from Norfolk & Western Railroad, ventured into NASCAR. They were the first airline to do so. They sponsored Richard Childress’ team from Ricky Rudd to Sterling Marlin. This iron-on patch is 3.75″ wide and 2.5″ deep. Incidentally, Piedmont was the 10th largest airline in the U.S. at the time. I think United owns the name now.
