This is a vintage The Specials t-shirt, I think this is 1980s, it's a soft cotton blend. The shirt is in ok vintage condition. No holes but armpit staining, some stains on the collar and also some stains on the back. I would guess this is a vintage size medium, it fits more like a newer size small.

This is a used vintage t-shirt, it isn't in mint condition. Please check the measurements, there are no returns for lack of fit. 

Length is 24.5 inches, sleeve is 6.25 inches, chest is 17.5 inches across armpit to armpit, shoulders are 15.5 inches across the back.
