A friend of mine recently came up with this shirt. Through some research, he believes that it could be from the 1967 USGP @ Watkins Glen, though that is just a guess. The names that can be identified are:
- Graham Hill
- Dan Gurney
- Denny Hulme
- Mike Spence
- Jim Clark
- Michael Parkes

The question for you, is: Who else autographed this shirt? Can anybody confirm which race it was from?
