This book gives details and statistics about underground subway systems around the world. There are 10 large subway systems featured, including New York, Mexico City, London, Paris, and Tokyo. The statistics include when the subway system was first opened, how many passengers it carries a year, how many lines are in the city, and the distance the tracks travel.

Each subway system includes a search-and-find illustration with objects to look for hidden in the artwork. I love the cartoon illustrations and how the objects are hidden so cleverly in between train cars or behind passengers. The art is brightly colored, and there are tons of little details in each scene that make it special and interesting.
I am really impressed with how this book is organized. Some of the pages are cropped so that you can flip to see the people inside of the subway trains. It’s a smart and effective design.
