Thanks, Dietrich -
That one was available as a Richard Cox / Vanishing Vistas 6x9" postcard back in the early seventies, but I'm pretty sure it's now out-of-print. He liked the third one too - except for Olaf Rasmussen's VW - and in the days before PhotoShop it was too much trouble for him to paint out the car. (Personally, I rather like having the car in the shot. It adds the feel of a race and helps to date the photo as well.)

p.s. That's Jim Shawcroft firing #484. He worked for the C&TS in the early to mid-seventies.
