i agree with mosh..........find another line of work))))))
as for COPYRIGHT on race car numbers, its open ended in some aspects.
all my years of paintin race cars, i cant tell you how many "local" race cars bear the same numbers as the NASCAR cars!!!!! every one i ever lettered, the guy who owned the car would show me a picture of the NASCAR number he wanted his car to have. now some like #3, if your resellin the same stickers they sell..........they will find you. i think they go a little easy on "local" RACE CAR numbers.
heres a "local" track car i did all freehand, i think, it was 1987-88, and long before dale jr. was old enough to drive))))))))))))))
