There, she met many Cubist artists and began developing her own style of Cubism. She became close friends with Juan Gris, a Spanish Cubist painter, who heavily influenced her work. Blanchard joined the Section d'Or, a Cubist art group Early paintings, such as "Woman With a Fan" , show flat, interlocked shapes. Her unique style evolved to become more figurative and traditional over the years; her paintings became harsh, with bright clashing colors and melancholic themes. The resulting artwork was very emotionally expressive. Demand for Blanchard's art skyrocketed after the showings 1920 in France and Belgium, and the 1921 exhibition at the Society of Independent Artists. She came into contact with significant art dealers, but due to the adverse economic situation which followed, many collectors stopped investing in her work. She became financially dependent on her friend, Frank Flausch (1878–1926) until his death. Without Flaush, Blanchard was able to sell paintings to galleries in Paris and a few private patrons. In 1927, Gris died. Blanchard was severely affected and fell into a state of depression. Her sister, Carmen, and nephews came to live with her in Paris, alleviating her loneliness but worsening her financial situation. In her deteriorating health, Blanchard turned to religion and considered joining a convent, but never did. She continued painting to support her sister and nephews. Blanchard's health gradually declined over the following years. She contracted tuberculosis, making it impossible for her to paint. On 5 April 1932, she died at age 51 in Paris. Blanchard's work was featured in the Botin Foundation of Santander, Spain during 2012–2013. The Museo Nacional Centro de Arte Reina Sofía, Hood Museum of Art, and Courtauld Institute of Art display original works from Blanchard. Blanchard was described by Gris as "[having] talent." Jacques Lipchitz wrote about her, saying that Blanchard "was a sincere artist and her paintings contain a painful sentiment of unusual violence." Diego Rivera described her work as being "pure expression." Birnbaum, Paula J. "Women Artists in Interwar France: Framing Femininities". Aldershot, Ashgate, 2011. Madaule, Liliane Caffin.
