Pop-up book needs a lot of mechanism to hide the content while the book is closed, and the 3D part must be able to stand when the book is opened.
This is a unique MOC from Patrick B. First, he made a 2D MOC (a book), then he made another 3D MOC to tell the story. LOL.
Well, this is not an advertisement, but i believe Lego minifigure lovers should own 1 of these books. It is the only complete book for the collectors as reference to aid in their hobby.
