The idea for the clip boards would be for kids to use for coloring while sitting in strollers and for characters to sign the index cards. I know not every parent wants to wait in line every where for characters, but occasionally they see a character or two and want thier autograph. And a buck for a pack of index cards is better than spending 5$ or more for a book, if you don't plan on using it. And you might help the kid behind you who doesn't have a book, but thinks that they have to have an autograph just because every one else does. Sometimes kids like to draw pictures to give to characters or write notes. I saw this alot when I was a photographer, and would keep a stack of index cards in my pocket.
