I like this sign I saw in a magazine / book / music shop in Auckland on the weekend: it’s direct, fun and in a style appropriate to the shoppers this business attracts yet clear in the point it makes.
This sign is far better than a dry sign saying don’t damage the books. Sure it is in your face – but in a style appropriate to eh magazines it is placed above.
Interestingly, I did not see one damaged magazine or book in this shop.
