Mary Sully (1896–1963) was a Yankton Dakota avant-garde artist.[1][2] Her work remained largely unknown until the early 21st century.[3]

Sully is best known for her colored-pencil triptychs and "personality prints," which often depicted celebrities such as Amelia Earhart, Gertrude Stein, and Greta Garbo. Her panels, characterized by abstract forms, symbols, rich colors, and symmetry, often appear kaleidoscopic in nature.

Her designs draw from and incorporate classic Native American designs — specifically Navajo textiles and Plains parfleches, painted rawhide containers — while also aligning with the Art Nouveau and Bauhaus movements.

Although she was active during the early decades of the 20th century, when Native American art and Art Nouveau were gaining prominence in mainstream fine art exhibitions, Sully was considered revolutionary for her synthesis of these two genres.

Early Life and Background
Mary Sully was born Susan Mable Deloria on the Standing Rock Reservation in South Dakota in 1896. She was the daughter of Tipi Sapa (Black Lodge), or Philip J. Deloria, and Mary Sully.[4] She was the great-granddaughter of the respected 19th-century American portrait artist Thomas Sully, known for capturing the personalities of America’s early celebrities, including the figure of Andrew Jackson immortalized on the twenty-dollar bill. She was also the granddaughter of military officer Alfred Sully.[5]

Her sister, Ella Cara Deloria, was an anthropologist with whom she traveled extensively throughout the United States, visiting many Native communities and observing the art that was integral to their daily lives. Sully also spent much of her time in New York City, drawing inspiration from the thriving art scene there.[
