Pinkney's retelling of the Aesop fable is really beautifully illustrated. It's also wordless, or very nearly (little squeaks from baby mice and the hoot of a hunting owl maybe don't count) so can be enjoyed no matter the level of literacy or language held. I saw a brief YouTube interview of him a few minutes ago, after reading the book, in which he said that he did the illustrations first, planning to add the text later, before realising once the pictures were complete that the book didn't need anything else, and I thought that was interesting. It doesn't have the knock-out wow factor of some other wordless stories I've seen (I'm still blown away by Shaun Tan's The Arrival), but I enjoyed it even so.
