Simple and sweet picture book about Leon, a small, school-age boy who has just moved to a new place in the city, is often alone, and invents an imaginary friend, Bob, as his companion. One day, he ventures to make a real friend of the boy he notices on his street. He realizes that he is on his own, really - Bob is not there. He gathers the courage to knock on the neighbor's door, and finds a new friend whose name is, coincedentally, Bob!
What makes this book a real standout, however, is the illustration. Watercolor wash with black ink outline - simple, gentle, and compelling. The setting appears to be Normandy, featuring 1920's or 1930's apartments with masonry architecture, Mansard roofs and turrets, and two-story interior ceilings. Tall wooden doors, long drainpipes, and simple interiors seem to dramatize the sense of isolation Leon feels, but it's mitigated by the warm sunlight entering each room and the inimate perspective of each page as a "scene". The art makes you grab the title off the shelf - the sweetness of the story appeals to young children and adults.
