When the fun of Actual Size is over, there's still hope. He did another one, and this time it's prehistoric animals. So you get to put your hand up to the pictures on each page and imagine just how big that prehistoric creature really was. This is an amazing book for giving children a sense of how large something really was. Helps them to put things into perspective along with handing them a gallon full of wonder! Just great for kids who like to think and imagine and who are captivated by the power of a dinosaur. Ages 4-8
