As others have stated, Champ produced some of the highest quality decals ever made. Apparently they were printed with a precision high definition letterpress using special paper and ink imported from Britain. I have a relatively large collection of their alphabets and they hold their colors and still work perfectly 30+ years after they were printed. Microscale supposedly uses the same techniques, but I don't feel their products (which don't cover nearly as extensive a range of roadnames as Champion did) are of quite the same caliber as those Champion produced.
