Query: Great for 4 year Cars fan!

My 4 and a half year old son LOVED this sticker book. I bought it just after the movie came out and he didn't put it down for 2 hours ! It would have been perfect for a long trip. Now that he's four these types of books are great--finding the correct sticker to be placed in the right spot--then he would ask us to read the caption.
