The surprising and ingenious system of moving and folding the pages of this book allow readers to discover the illustrations and text that turn it into an infinite book. Juan Azpilicueta's design means you can read the pages in different ways, in an never-ending reading game. Infinite Books. The Chicken or the Egg? Is much more than a book, its movability helps to develop motor skills and visual comprehension and reading ability, while stimulating imagination and knowledge about the lives of animals and the cycle of life.
