While the sisters' collection remained private until Etta's death, Etta occasionally lent pieces to museums for exhibition. Claribel had willed her artistic paintings to Etta, spelling out in her will that these paintings should be transferred to the
Baltimore Museum of Art if there was an interest in modern art. The bulk of the collection eventually went to that museum by Etta's will, and a new wing was added to the museum for the
Cone Collection in 1957. The collection consists of approximately 3,000 items the Cone sisters had acquired over 50 years. The collection has not only French art, but American art as well, including over 1000 American prints, illustrated books, and drawings. Among these were cloth goods,
costume jewelry, tables, chairs, and cabinets. The Cone sisters also acquired many of Picasso's works, and among these were 114 prints and drawings from his early years in
Barcelona and from his
Rose period (1905–1906) in Paris. A portion of the Cone art collection, including many Matisse
lithographs and bronzes, resides at the
Weatherspoon Art Museum at the
University of North Carolina, where the Cone Mills were located. Moses Cone's vacation home
Flat Top Manor was located in nearby
Blowing Rock, North Carolina, and the Cone sisters often visited their brother there. Other visitors included Julius Cone – another of the Cone siblings – and his wife Laura, who was an alumnus of the University of North Carolina. Laura was aware that the Weatherspoon Art Gallery had been formed on the campus in 1942, and she asked Etta if she would be interested in making a gift of art. In her will, Etta left an endowment to the Weatherspoon Art Gallery consisting of sixty-seven Matisse prints, six Matisse bronzes, several modern prints, and art by Picasso,
Félix Vallotton,
Raoul Dufy, and
John D. Graham. ==Death==
