I asked my DNiece(3-almost 4) if she wanted an autograph book, she said she did. I'm not sure if she will be into doing it so I just bought a dollar store one-not Disney. She can't read so I have been purchasing Disney stickers, trying to get as many characters as I can find to add to the page with the autograph. So far I have Mulan, the Disney princesses, Mickey and the gang, Monster's Inc., Tinkerbell, Winnie the Pooh and friends and Dalmations. I also found Alice in Wonderland-not Disney.
I have heard that they have ones at DL where you can put a picture of your child on one side with the character and have the autograph on the other. They don't hold many autographs/photos and they are more expensive than the other kinds.
