I purchased this book for a little friend of mine who absolutely loves dinosaurs. When I received it I was thrilled with the contents of this book. The pop outs are fantastic and literally bring the book to life. After I received my first one, I went back and ordered two more, one for my nephew and one I am going to keep (for a grandchild of my own someday).This book is definitely a "must have" among all the dinosaur loving children.
