Illustrations from Ezra Jack Keats’ classic 1962 book The Snowy Day are being featured on new forever stamps from the United States Postal Service.

The Caldecott Medal winner is heralded as one of the first mainstream children’s books with an African-American child as the central character. Keats drew Peter exploring the fresh snowfall and playing in his neighborhood.

“Ezra wanted all children to be able to see themselves in picture books,” states Ezra Jack Keats Foundation Executive Director Deborah Pope. “He transformed the landscape of children’s literature with the diversity of his characters, and his work was embraced across ethnic and social boundaries.”

Art director Antonio Alcalá of Alexandria, Virginia designed The Snowy Day USPS prints. The postage stamps are available for purchase at store.usps.com.

“I am honored to represent the Postal Service as we dedicate four stamps that feature an iconic image that has had a positive impact on children for more than 50 years,” says U.S. Postal Service Government Relations and Public Policy Acting Executive Director Roderick Sallay.
