Barter Books is an amazing shop. I live about 20 miles away and was in there the other week. What was intended to be a quick stop off ended up becoming an extended (and expensive) book-buying session.

Strange to think that, had that box of books not been bought, the poster may not have been found, and so wouldn't be adorning every kind of item conceivable. Bet the shop wouldn't mind earning commission on its use...
