Getting ready for monster book...

I would like to see a picture of this, if you could.

I don't have a SS of it on hand, but basically it has a picture of a book, and cover of the book changes color every 11 or so cards you get. This also increases the book's level. I have approximately 50 different cards, but my book's cover is green and it's level 3. I don't think that "special cards" (Boss monster Cards and Event monster cards) count towards your book's level.
