This fascinating, oversize picture book isn’t strictly about cities; it includes scenes of farms and suburbs as well as crowded city train stations and downtown department stores. But it bustles with the energy, variety, and ever-changing busy-ness associated with cities. There is no written story; instead, the book encourages observers to create their own stories as they follow the recurring characters on their journeys through the detailed scenes (each shown in winter, spring, summer, and fall). Unique, imaginative, and engrossing.
