Marie Hall Ets (December 16, 1895 – January 17, 1984) was an American writer and illustrator who is best known for children's picture books.

[1] In 1960 Ets won the annual Caldecott Medal for her illustrations of Nine Days to Christmas, for which she also co-authored text with Aurora Labastida.

[4] Constantine Georgiou comments in Children and Their Literature that Ets' "picture stories and easy-to-read books" (along with those of Maurice Sendak) "are filled with endearing and quaint human touches, putting them at precisely the right angle to life in early childhood.

"[5] Play With Me, says Georgiou, is "a tender little tale, delicately illustrated in fragile pastels that echo the quiet mood of the story.

"[6] In 1970, her transcription of the autobiographical stories of Ines Cassettari, whom she met in Chicago in the years following World War I, was published as Rosa: The Life of an Italian Immigrant.
