Faded, the "real" Snell sticker is on the inside - usually under the soft liner fabric. You'll most likely have to dig and peer and look and use a flashlight and keep trying, you'll find it sooner or later if it's there. The past ones have been rotogravures -- that is, shiny "paper" that looks darn near like foil, and has the printing on it. You'll likely have a hard time reading it, too.
But that all contributes to the difficult in making copies and therefore "certifying" a non-legal helmet. Dig into the liner and report back, if you please, when you find the sticker. Tell us what it says, too, okay?
