I found a Simpson full face with a Snell tag that dates to 1975 at The second hand store for the pricely sum of $5 it even fits my melon. I would post a picture but I have not entered the 21st century in the field of Photography yet.
Damn that's cool!! I want to gold flake my bike when I'm done and am trying to find one like that. I got a big melon, though...
