I came across this site on vintage RC cars today, well, more specifically I came across the decals on the site. There’s quite an impressive collection here, kept presumably until the guy can get them all converted to EPS files. If they were higher resolution scans, I guess it wouldn’t be too difficult a process to use LiveTrace in Illustrator. Mind you, looking closely, a fair few of them have slight registration problems in the printing, so auto tracing would necessitate a fair amount of rework.
Still, just look at all those logos! All those swooshes and go-faster stripes! I love racing decals anyway, ever since I got to go with my Dad to vintage races at Oulton and Donnington Parks. They’re great. Vroom!
