Graham traveled throughout the United States with her husband and then they later traveled worldwide. They decided to live in Riverside, California, and Edward entered the real estate business there. After her husband died in 1967, Graham moved into a house that was close to their old one. She later made around 20 scrapbooks of Grant's life which were microfilmed by the Archives of American Art within the Smithsonian Institution. In 1984, she was nearing blindness and moved to a nursing home, later dying there on December 14, 1990. In 1993, her memoir, My Brother, Grant Wood, was posthumously published by the State Historical Society of Iowa.
