Saw this picture on Pinterest (love that site) and it brought back a very fond memory.
Many many many years ago 😉 we had a great old market at the top of our town. Use to do loads of great stuff, including a book stall, he had hundreds of books, all in cardboard boxes, all facing out so you you see the titles.
He had them all sorted into genres and he didn’t mind if you spend hours looking through them, he also had a scheme where he would buy your old books. Or just a straight swap.
A lot of people use to use that idea, bring him the books and then buy more. There was also a few times I’d seen him give a book away to someone who couldn’t afford one.
