many of these race car numbers are HAND DRAWN. when paint was the way to go......we did race cars freehand.......and drew the numbers on the car from memory. no idea what they are.....we just did what we thought would look good. here are 3 i did might look close to a font you know but it aint.......and if they are vinyl or print, more then likely they were photographed and scanned for that person.......who had that number for many years.
