Flap flap flap ... Has there ever been more movement between two covers? This book brings immense joy! No one has ever had such an idea - and yet it is so fantastic: Lisbon graphic designer Madalena Matoso utilizes the necessity of opening and closing books in a way that brings pure delight to everyone - young and old alike. With a loud "Doing," two bowls kick off a series of movements and sounds that follow. Next, two mouths come together and kiss twice. This is followed by three instances of opening and closing - a knock on a door: knock knock knock. The sequence continues with 13 strikes of the triangle (pling pling ...) leading up to a multi-voiced applause: clap clap clap! This book is both a counting book and a colorful event that only works with the act of opening and closing the book. Doing! Fl.
