Blackstone spent the early part of her career in
Glencoe, Illinois. She designed and built the first
bungalow in Glencoe, with a separate painting studio out back. She spent part of World War I in New Mexico working for the U.S. government, which tasked her with painting Native Americans and their environments. During the war, she also produced
range-finder paintings to help train military gunners. In 1920, she moved to New York, where she died in 1939. Blackstone's portraits were praised for their individuality, directness, and mastery of technique. One art expert commented: "How does she get that flesh color? It is as luminous as life itself." Among those she painted were soprano
Amelita Galli-Curci, singer
Nadezhda Plevitskaya, architect
D. Everett Waid, pianist
Stell Andersen, Mrs.
Frederick D. Underwood, Mrs.
