Original NASL logo patch from 1975. There is a bootleg of this out there too, reproduced during the USL era. The easiest way to tell the difference is that the bootleg has has thin, single thread stitching on the chevrons. The typeface weight on the bootleg appears to be lighter, with looser kerning. Buyer beware, however. It’s easy to tell that some of these are definitely fake, but in a case like this, where the construction method matches, you have to investigate the source to be sure.
