I bought both of my first racing shirts on the same weekend and they are on the bottom of a dresser full of t-shirts that have.....shrunk in size over the years :rolling

A Sammy Swindell Old Milwaukee shirt and a Lloyd K Stephens Ofixco Special shirt with Ronnie Shuman.

My first USAC shirt and I still have it is a Roy Caruthers shirt (aka "Pizza Man" if your reading Roy Boy..inside joke) from the 5c Crucean years I believe 1991 or so.
