My grandkids have an architect for a dad in Seattle, WA so after I first met the author years ago while he was visiting upstate NY, I knew this book was a keeper and bought it for our own library. As adults we enjoy the photo/artist view of the city by looking beyond what is first visible to the ordinary eye. It is a great way to get the young viewer to see detail after learning numbers. We purchsed both books...City by Numbers and its' partner, Alphabet City. THey are great for anyone interested in photography too.
