Great group!!
Do you mind sharing the ISBN of the Hodder & Stoughton in the middle?
I've been looking for the proof with the silhouette on the page edge since someone first posted it here but haven't been able to find a copy. I only know about it because of this site and have never seen it available anywhere... I know it's numbered and limited to I think 300(?) copies. If I'm not going to be able to find the proof I'd like to have the Hodder & Stoughton version at least!
