Thanks to suggestions on the boards, I ordered the Disney Junior Encyclopedia of Characters for my friend's son to use instead of an autograph book. It was around $11.00, and they loved it! We have a trip coming up soon and I just went to order one for my two kids....and the price went up to $41.00! I have no idea why. I am hoping that someone knows of another book to have them sign or has any other cute ideas for character signings. Thanks in advance!
