I've seen a few labels on unrestored car that I believe were original to the car. One I pulled up was from a 68 NJ example but I know of no one reproducing them
On other years have seen shipping labels on some tire and wheel combination (space saver) not not certain that was for all of them. ANd as Bob mentioned have seen a side wall square stamp, printing on the thread as well as writing on the side wall depending on year and application
