My son loves geography. He has a globe and map of the world with each nation's flag and a lot of books. I thought I had this subject covered until I ran across this the 3D Atlas. This book is amazing and your child doesn't have to be into geography to love it.
There are 50 photos for the 3D glasses. They make the mountains pop off the pages. He still oohs and aahs when he looks at it and not to worry, when the glasses are eventually lost (you know this will happen), the book still manages to keep their interest. It is written for a child and the facts from around the world will capture their imagination and expand their view. My son was particularly fascinated to learn that chewing gum was against the law in Singapore and there were severe punishments for littering! It comes filled with all kinds of fun facts that appeal to kids.
This book is perfect for a gift - I just ordered one and discovered it was much cheaper here at Amazon. There is a whole series of books in the 3D line (I can recommend the Extreme 3-D Scary Bugs! (Extreme 3-D) one as well) by different authors.
