The Snowy Day is a 1962 children's picture book by American author and illustrator Ezra Jack Keats. Keats received the 1963 Caldecott Medal for his illustrations in the book. It features a boy named Peter exploring his neighborhood after the first snowfall of the season. The inspiration for Peter came from a Life magazine photo article from 1940, and Keats' desire to have minority children of New York as central characters in his stories. Peter appears in six more books growing from a small boy in The Snowy Day to pre-adolescence in A Letter to Amy.
