Jeanne Chamberland, left, 88, of St. Agatha and her sister, Lillian Bussier, 84, of Lewiston, laugh after viewing a photo Friday of their mother, Emma Gagnon, pouring buttermilk. The photo, captured by Farm Security Administration photographer John Collier Jr. while documenting the Gagnon family’s potato farm in Frenchville, is on display at the Maine State Museum in Augusta. Gagnon, a mother of 11 children, passed away from tetanus at the age of 42, two years after the photo was created. It was the first time Chamberland saw the photo.
