Thanks SoCalRat, that's a good start.
The Rat Fink stuff is cool. I'm interested more in the retro stuff than the modern looking stuff.
The post about the Not Rod collector cards probably got me on this topic. Something like that on a shirt is cool.
I always wanted the Gulf racing jacket Steve McQueen wore in the movie "Le Mans" it had a racing stripe going up the front with a Gulf logo on it. The Super Chevy shirt with the orange stripe is a similar-looking thing.
