Black-and-white candid portrait of Gabriela Mistral, an older woman with a warm, radiant smile, seated comfortably in an armchair in what appears to be a study or living room. She has short, wavy gray hair styled softly, and wears a dark tailored jacket or coat. Her expression is joyful and engaging as she looks directly at the camera.
