Before there were 3-D TVs and movie theaters, there were popup books. And what can be cooler than a popup book full of dinosaurs!?!? The Encyclopedia Prehistorica Dinosaurs : The Definitive Pop-Up is full of fascinating facts and lighthearted good humor about popular dinosaurs as well as many lesser-known varieties. There are more than 35 popups, and each of the six spreads feature one spectacular, large pop-up as well as booklets of smaller pop-ups and text. This book is a magnificent display of paper engineering and creativity — an astonishing book that will be read, admired, and treasured forever.
