Here is my copy of the official 2000AD sketchbook with better quality paper. So far it has twelve sketches, usually paid for and therefore more detailed than the notebook Dredd head doodles. At the moment I plan to auction this for charity once it is finished but there are another ten pages and I only get one or two sketches at each convention so it will be a while yet.
You can see the sketches so far in this photobucket album. And just to whet your appetite here is a marvellously creepy Judge Death by Dave Kendall.
