I know nothing about that site - no relationship to this site at all.
Regarding the picture book - that's your lot I'm afraid - there were only 8? (have to go check it again) pages - the book looks thicker as there were actually the same pages twice over bound together to make the book look longer. I was hoping that missing page that was just recovered from David Morrissey's copy of sawing the logs might have contained Kidder actually, but it was also just Billy & Icky. Some of the scenes it depicts don't occur in the series - I don't know if these were scenes that were in the original script, or just the artist using some creative licence.
I think the book is a rather wonderful memento of the series. Very early in the development of this website a fellow One Summerite and friend emailed me and theorised about what had happened to that picture book, and I admit I was quite cynical about imagining such props would still exist. So imagine my delight when I learned they were given as gifts to Spencer and David at the end of the shoot.
But the picture book doesn't tell a story really, which would have been a nice. Maybe someone should continue it?? *lol*
