Celebrate the snowy season wherever you are.

One of the best parts of sending out holiday cards is choosing a festive stamp for the envelope, and this year, the country’s favorite wintertime children’s book is being immortalized in stamp form. The book is Ezra Jack Keats’ The Snowy Day, which was first published in 1962 and has been a beloved resident of bookshelves everywhere in the decades since.

The Snowy Day follows a young boy named Peter as he embarks on adventures in the snow and takes in the wonder of the season. The book won the Caldecott Medal in 1963, an honor which recognizes the most distinguished children’s picture book published in the U.S. each year, and it is also noteworthy for being the first picture book with an African-American protagonist.

These stamps show Peter playing in the snow in his bright red snowsuit, making a snow angel, packing a snowball, sliding down a snowy hill, and inspecting his footprints in the snow. While some Southern states aren’t expecting much of a snowfall this year, thanks to these stamps and the four snowy scenes they depict, we can all add some winter weather to our holiday greetings and celebrate the wonder and joy of the season, just like Peter.
