Here is one I did back in '89 of Brundle's Jaguar at the Silverstone 1000kms Group C race.
It was 30x20ins and commissioned by the marshals at Silverstone. They all clubbed together to have it done and presented it to one of their team who was leaving - John Higgins from Northampton.
I put some marshals here and there including some pushing the Roy Baker Tiga in the pit road, due to it's purpose.
Hope you like it.
