To mark the publication of Dan and the DeadI’m giving away a signed copy. But since it’s no fun just handing books out willy nilly, you’re going to have to work for this one. So here, for your coffee-break amusement, is a pair of identical pictures of our hero, Dan. Identical, that is, except for one small but notable difference.

Click for a closer look at the pictures, if your browser supports that. The difference is subtle, but should be visible even at crappy blogger resolutions. And if you really get stuck, ask a friendly child to do it for you!
