Children's book: Sense títol

In this book there are characters (faces a mica gargotejats) and an author (xxxxittt!, is treballant). Yes, because the free face is not finished! Però ja that I am here and with that voleu a conte, they will do us the favor. (Bé, ho they will try...!) A book by Hervé Tullet full of surprises, like the theater!
