"The Book with a Hole" by Herve Tullet blasts a hole through the middle of the book itself. It's full of fun drawings and inventive ideas.
Sometimes the Hole is an eye the reader can look through, sometimes it is a mouth and the reader's fingers make the teeth. The next minute it is a plate (with food drawn by the reader on a sheet of paper behind the book), an obstacle to jump across or a saucepan. It's crazy. It's a Book with a Hole.
The book is best for ages 3 to 8 years old. You can buy it online from Book Depository
