After Karl’s death in 1984, she shared a studio and gallery with her artist daughter, Elizabeth (Bebe) Wolfe, and was still actively painting several mornings a week until ill health and frailty finally prevented her from working at the age of 92. She died peacefully in her beloved home at the age of 96 in 2009.
Her work is in the collections of the Mississippi Museum of Art, the Lauren Rodgers Museum in Laurel, the Huntsville and Montgomery Museums of Art in Alabama, the Library of Congress and the National Portrait Gallery of the Smithsonian Institute in Washington, D.C., as well as in many distinguished private collections.
In 2005 the University Press of Mississippi published a book of her work, titled Mildred Nungester Wolfe, edited by Elizabeth Wolfe, with an introduction by Mississippi writer Ellen Douglas.
