Slightly off topic, but related to AB.
Just over a year ago, I went to one of the two live shows which were taped and editted to form the Good Easts 10th anniversary show (it was great fun). The programs for the event were pretty standard several stapled pages, with a couple of cards gum attached inside and removeable. First card was like a postcard, the second card is a paper-backed sticker, about 2 by 4 inches, with AB's signature in red marker (not auto-pen, actually signed) clearly done to allow one to adhere it inside a book and have a pseudo-signed copy.
I thought the signed 'bookplate" was a thoughtful idea, and on the way out I noticed that there were stacks of programs which had not been handed out. Since we were at the second (evening) performance, I thought they could not be of further use, and asked an usher if I could take extras.
Which is how quite a few of these made their way to my home. I have four of the programs left, with the sticker autograph, and would be happy to mail one to any AB fans (up to four, of course) who care to provide a mailing address by PM. They aren't "valuable" but are fun to have to put into his books.
On topic, I think his rules of engagement are generous.
