Ana Pez suggests that the game of interactivity is possible in the book printed over a period of time where these projects seem to be limited to the electronic realm. Printed in two inks and with an intelligent use of red acetate lenses that make orange ink invisible, this book is plain to all: he who undertakes a child hiding in a cardboard box, convinced that he is invisible, and he who makes adults who come across this character, without being able to see what he discovers: a jungle full of ferocious animals, a trip to space, a sea full of birds and sirens and other fun landscapes. This album emerges from the reader in a novel and fun reading experience that will be enjoyed by kids and adults alike. Surprise and discover the hidden history in these pages!
