I've had this hat for years, trying to figure out who's signatures they are.
For some reason I think they're fishing related, but don't remember at this point
I thought I would recognize most of them, but I don't know any of them. I have followed MX, SX, AMA, WSB and MotoGP for 30+ years. I don't know any of them. Being a red hat I would guess it was from the 90s. Maybe crew?
