Happy Grandma Moses Day! In the two decades following her debut solo show at Otto Kallir’s Galerie St. Etienne, Anna Mary Robertson “Grandma” Moses forged her own path to celebrity, creating upwards of 1500 paintings and exhibiting across North America and Europe.
In 1960, New York Governor Nelson Rockefeller proclaimed September 7th “Grandma Moses Day” in honor of the self-taught artist’s 100th birthday. She celebrated the milestone and honorary holiday in the company of her family, with a very large cake.
