Georgia O'Keeffe
Tuma first met O’Keeffe in 1964 and during the following decade the two artists discovered several common interests, including an enthusiasm for each other’s art. This is shown from the various handwritten letters between Georgia O'Keeffe and Tuma. An exhibit of her work hung in Edens Gallery during November 1987 during Columbia College’s “Georgia O'Keeffe Centennial Celebration.”
