The poem about Mary and her little lamb is one of the most popular rhymes in America, but did you know that the rhyme is true? There once was a little girl named Mary who saved the life of a tiny lamb. The two became best friends, and that little lamb followed Mary everywhere - even to school, where the poet John Roulstone visited and immortalized the two in verse.

With his trademark folk art style, Will Moses paints the true story behind the famous nursery rhyme and shows how Mary went from being a small-town Massachusetts girl to an American folk hero.
