As I mentioned the Tag states it is a one size fits all. HOWEVER shirts back in the days seem to have been sized differently that today So I have taken Some approximate SIZING measurements, which are: from back collar to bottom 30 inches, from armpit to armpit 22 1/2 inches, and from collar to the end of the sleeve is 15 inches. I have taken a picture with a tape measure in it to give you an idea of measurements. I did wash the shirt, on gentle cycle, but I was too lazy to iron the shirt before I took the pics, so there are some creases in the pictures.
I recently acquired a large lot of vintage Mostly Heavy Metal and Classic Rock Concert Tour, and Sports Graphic Tee shirts (although there is a clash shirt so some punk rock lol). They are mostly from the 1980's with a few from the 1990's. Keep an eye on my page to see the other shirts over the next few weeks.
