One , Two, Where's My Shoe?, from Phaidon, is a nice little book where you have to play through the pages and find the shoes. Did it vanish into thin air? Does it sail on the high seas? Or has it jumped on the train?
Look carefully, it might be hidden in a juicy ham, or in a soldier's elegant moustache.
