English: Ingri (December 27, 1904 – October 24, 1980) and Edgar (September 30, 1898 – May 1, 1986) Parin d'Aulaire; two writers and illustrators of children's books in the 20th century.
Per Ola d'Aulaire writes: "The attached publicity photography was passed along to me by my parents, children's book authors, Ingri and Edgar Parin d'Aulaire upon their deaths in Oct. 1980 and May 1986 respectively, along with other materials. The photographer is unknown and the photograph is undated but I can attest that it dates from the 1930s. It was most likely commissioned as a work for hire by my parents' publisher at the time, "Doubleday, Doran", as a publicity photo to accompany the publication of their Caldecott Award winning book, "Lincoln" in 1939."
