I rather liked this series of quirky number illustrations by Tim Burton. If you have an afternoon spare, I thoroughly recommend a trip to the MOMA to see a jam packed retrospective of his work. As you probably know, his work can be rather peculiar at times so if you take younger children you may want to navigate them away from his more bizarre pieces. However they’ll delight at the moving sculptures and love the glow-in-the-dark room where everything white lights up!
