I bought this book when I was in Paris (my son loves the Eiffel Tower) without knowing this collection. From a quality perspective, this book series is excellent with laminated pages and solid yet my son who is 4 years old is far from being a tender with its business. The quality is very good explanations, the design is simple but complete. For the case in this book "Paris" is in town with the main places but not that. We also see the subway, markets, pars, Paris in cross section to show life underground (metro, parking, shopping malls, sewers ...) It's very rewarding and it opens a lot of questions to children. Unquestionably one of the favorite books of my son.
