Georgia O'Keeffe was one of the world's most influential female artists - in 2014, her painting "Jimson Weed" sold for the highest price ever paid for a work by a woman. Famous for her vivid oil paintings of flowers, landscapes and animal skulls, she lived and worked in the wild dry canyons and deserts of New Mexico in the southern United States. Lucy Burns speaks to her former assistant Agapita Judy Lopez. PICTURE: Journalists view 'Jimson Weed/White Flower No.1' by Georgia O'Keeffe at Tate Modern on July 4, 2016 in London, England.
