What about a double sided version where the inside contains something of value? Perhaps a called out spot for a flash drive containing the book, or a QR code to the book/amazon page/etc, or perhaps a little "guest log" so people could open it up and rate the book? Would be an interesting experiment/art thing

In fact, if you did what the others down below suggested (the Amazon Kindle scraper) then the inside could automatically contain when you purchased the book which would be kind of cool
