This book is a compilation of four seasonal Rotraut Susanne Berner books. The main interest of these books is to generate awareness among children. Without text, the boards contain so many details and objects that every night, we can change history. One evening the child is seek out the names of objects and the next day he's asking the questions. It is a very friendly reading for the child and the parent and this leaves an opportunity for the one as for the other to do the stories. The other advantage of this edition is that it amounts to two to three times cheaper than the 4 books individually.
