A small t or casual shirt equates to a 36-inch chest. Casual shirts are small, medium, large, or extra large. A dress shirt is identified by the neck and sleeve measurements; a small having a 14-14 1/2 inch neck and 32/33 sleeve length unless you are especially tall, then it might be 34/35.
A large T-shirt in 1970 seems really small now. Everybody was skinny, and shirts were tight back then. The garment industry has changed the sizes almost every 10 years. The shirts are wider and longer now. When we do our auctions, we always make sure that we specify the dimensions.
