Frida Kahlo, Mexico’s heroína del dolor, the heroine of pain. In her 1932 painting Self-Portrait on the Borderline between Mexico and the United States, a defiant Frida straddles an imaginary boundary between Mexico and Detroit, where she was living at the time with her husband, the muralist Diego Rivera. The Mexican side is strewn with skulls, ruins, plants, and flowers with thick roots burrowed deep into the soil. The Detroit side contains factories, skyscrapers, and plumes of smoke—an industrial city that hides the natural cycle of life and death.
