My daughters and their friends have lost so many things over the years (camera, several autograph books, cellphone, and a Disney merchandise bag with ticket & money in it). The lost stuff has been turned in every single time.
One time my daughter lost her camera. The only identification it has on it was a sticker of the Pepperidge Farm Goldfish. We called lost and found. The found it and mailed it to our home.
I am so glad that you daughter got her autograph book back. Just a suggestion to everybody, alway have you name & address on your autograph books, cameras ect. I found that all thost mailing address labels that we get in the mail come in handy for just this chore.
