In Adios Amor, the discovery of lost photographs sparks the search for a hero that history forgot—Maria Moreno, a migrant mother driven to speak out by her twelve children’s hunger. Years before Cesar Chavez and Dolores Huerta launched the United Farm Workers, Maria picked up the only weapon she had—her voice—and became an outspoken leader in an era when women were relegated to the background. The first farm worker woman in America to be hired as a union organizer, Maria’s story was silenced and her legacy buried—until now.

These are the photographs that inspired Adios Amor. They were taken by George Ballis, and can be found at Take Stock archive:
