Nancy Green was an American former female slave, who, as "Aunt Jemima", was one of the first African-American models hired to promote a corporate trademark. The Aunt Jemima recipe was not her recipe, but she became the advertising world's first living trademark.

Aunt Jemima was an American breakfast brand for pancake mix, table syrup, and other breakfast food products. The original version of the pancake mix was developed in 1888–1889 by the Pearl Milling Company and was advertised as the first "ready-mix" cooking product.
