if you have pirate lovers, they also have a pirates theme book. i didn't check out the price though, i had picked up a couple at the outlet store when it was here in Sacramento since my kids never even look at the front.
The Pirate is autographs only. The Blue is a picture insert. The pen that comes with the Blue Castle book is a blue gel pen that doesn't show up on the light blue pages - it also started leaking all over and made spots on my pages before I quit using it. I recommend you substitute the pen. It has an elastic doo-dad for a normal size pen to slide into just like the 50th book. In answer to the other question about duplicate autographs, I mainly like the idea that I'm updating the pics and just get whoever we come across.
Of course we are always looking for new characters but we get photos taken as well as the signatures. My daughter LOVES to look back at her time with them and even tells stories (like remember when Peter Pan took my book and went to take a nap on it?) I let her take the lead and pick who she wants to see
