Kahlo's interests in politics and art led to the next stage of her life. In 1927, she joined the Mexican Communist Party, through which she met fellow Mexican artist Diego Rivera, whom she married in 1928. The relationship was volatile and included a year-long divorce; both had extramarital affairs. Kahlo spent the late 1920s and early 1930s travelling in Mexico and the United States with Rivera. During this time, she developed her own style as an artist, drew her main inspiration from Mexican folk culture, and painted mostly small self-portraits which mixed elements from pre-Columbian and Catholic mythology. Her paintings raised the interest of Surrealist artist André Breton, who arranged for Kahlo's first solo exhibition at the Julien Levy Gallery in New York in 1938. The exhibition was a success and was followed by another in Paris in 1939. While the French exhibition was less successful, the Louvre purchased a painting from Kahlo, The Frame, making her the first Mexican artist to be featured in their collection. Throughout the 1940s, Kahlo participated in exhibitions in Mexico and the United States. She taught at the Escuela Nacional de Pintura, Escultura y Grabado "La Esmeralda" and became a founding member of the Seminario de Cultura Mexicana. Kahlo's always fragile health began to decline in the same decade. She had her first solo exhibition in Mexico in 1953, shortly before her death in 1954 at the age of 47.
