Picture 15 Santa Claus has been around for a fair few years now and there can't be many of us who don't understand what he's all about.

But what would happen if Santa turned up at an advertising agency looking for some advice on how he could make sure children got their Christmas list to him on time?

He might well find himself subject to a brand makeover in order to ensure his 'key message was better understood by his target market'.

And you can see what the subsequent brand book might look like by clicking here.

It's a very funny end of year read and not a million miles away from what I've seen happen to some charities who have taken the decision to re-brand.

With thanks to @rydesign for another great heads up and the people from Quietroom for the book itself.
