The Narnia Code - the T Shirt!
How's about this then? Those of you who have read Michael Ward's fabulous book Planet Narnia (OUP) - in which he convincingly argues that each of C.S. Lewis Narnia chronciles corresponds to a different plant in the Medieval cosmological scheme - will love this design by Dave Chisholm and Alan Noake. I think the idea is that it could be a T Shirt. I'd get one!
