I know with our homemade ones the reactions we get to them are the best! Last year when we went to the Silly Side show we saw Goofy and Donald first and Goofy made a HUGE deal of seeing his pick on the autograph book. I used an actual pic of stuntman goofy from the side show not just a pic of regular goofy, lol. Anyways Goofy ran over to Donald and basically shoved the autograph book in his face, it was so funny, lol, then when we got to Donald he did the same thing. The line was relatively short so the characters were really goofing off sort of speak LOL. My son felt so special that the characters were making such a big deal over his autograph book. I know Tigger ALWAYS makes a huge deal over our autograph books...always hopping and jumping around when he sees them.
This year I am hoping to turn the autograph books into more of a photobook/scrapbook as well so we will see how that turns out, LOL
