Want to have your portrait done by world-famous illustrator Paul Davis? It's the latest offer in our series of auctions to raise money for Comic Relief

All this week we are using the CR website to raise money for Comic Relief. We've already donated five subscriptions to CR (there will be five more tomorrow) and you can bid on a rare James Jarvis vinyl toy here.

Our next offer is very special indeed. The winner will get themselves along to Paul Davis's studio in London (we won't pay your travel, sorry), have a chat with the man himself (there may be tea involved, Wagon Wheels and Choco Leibnitz have been mentioned, no guarantees), Davis will draw you and you get the picture. But, warns Davis, "Don't expect a likeness – it'll be more about the person than what he or she looks like. Let me at them..."

We'll be announcing more stuff all week.
