I own this book and The Cities Book and they are the two best coffee table books that money can buy. This is a huge photographic encyclopedias of alll the countries in the world giving you interesting facts and the best things to see in each country.
It never fails to amaze me how my friends will pick the two books up every time they come round.
These books are a world apart from the Blue List type books that Lonely Planet do that are smaller and not very interesting to be honest. These books will last a lifetime and always be relevant.
