William Pène du Bois won the Newbury Medal in 1948 for The Twenty-One Balloons, and Caldecott Honors in 1952 for Bear Party and 1957 for Lion.
Some of his books (Bear Party , Lion) are picture books with a minimum of text, and properly classified as children's books.
Others, however, such as The Three Policemen, The Great Geppy, The Twenty-one Balloons, Squirrel Hotel, Peter Graves, The Giant, appeal to all ages. These books exhibit whimsical ingenuity in story and illustrations.
Though not usually so classified, these books seem to qualify as science fiction. Their interest lies more in their imaginative elaboration of ideas than in their characters. These ideas are exhibited in great detail. Some are fantastic, but many are plausible, and some (such as the Balloon Merry-Go-Round in The Twenty-one Balloons) might well be feasible.
A passage from The Twenty-one Balloons may serve to illustrate his style and method. In the story, the Explorers' Club of San Francisco is capped with its hemispherical cupola, painted as a globe of the Northern Hemisphere. The club decorates the cupola with balloons, in honor of a distinguished visitor. Du Bois writes:
