In the ideal follow-up to his stunning Caldecott Honor book , Stephen T. Johnson turns his talents towards numbers. Wordless spreads featuring impressively photo-realistic paintings of New York City invite readers both young and old to search for the numbers zero through twenty-one hidden in the images. From a sweeping 4 found in the span of an urban bridge to the 13 of a faded crosswalk, this is an intriguing new way to think about numbers and the world around you.
