Although the shirt quality is fine, it runs incredibly small. I bought an XL (this is the size of all my shirts) but it was skin tight. I felt like a human sausage. So, if your chest size is more than about 44 be prepared for a snug fit. If there had been a 2XL available it might have fit. The other XL t-shirt I bought fits perfectly. >>Just a general comment<< I would love to see books on Syd's artwork for sale on this site and not via 3rd party book sellers. rb
