I finally managed to fly to London from Barcelona and get my copy signed too, and a picture shaking hands with him.
I got there at 15:44 (the receipt says that

) and was with him at 17:51 (the camera says it again), so I'm probably on this picture of the queue.
pressld2, if I tell you my email could you send me those 3 pictures in full resolution, I could not take a picture of him alone that good. Thanks.
