I almost picked all of those, but I thought someone else would've already got them before I did. Plus I couldn't find a good snap of John Surtees - he was my first choice.
Then I found a photo of James Hunt in such a typically James Hunt situation, and I had to have it.
Edit: Has anyone got Jackie Stewart yet? I haven't seen him. Proper bloody talented racing driver right there.
Edit: Ah I see we already have two people with Jackie Stewart!
