I bought DS and DD hard covered photo albums at WDW. The outside has characters all over, plus a spot to put a 4x6 picture (like a frame-I use a pic of each kid in front of the castle). The kids get autographs in one of the WDW autograph books. When we get home, I scan the autographs into the computer, and shrink them down a bit. I then take a photo of each kid with that character, and combine it with the autograph into a 4x6 picture, print it out and slip it into the pages in the book.
This was DS's 3rd trip so its neat to see him with say Mickey Mouse at age 2, and now at 4. It was DD's (15 mos) 1st trip so instead of getting duplicate autographs, we just took photos of her with the characters. I already had many characters' autographs from DS's previous trips stored on our computer.
