A new exhibition at MoMA, Georgia O’Keeffe: To See Takes Time, displays over 120 works of the late American artist Georgia O'Keeffe, who's most known for her flower paintings made in the 1930s. But in an earlier period of her life, and also later on, O'Keeffe experimented with a series of works on paper, using charcoal, watercolor, pencil and pastel. These works and more are part of the exhibition which is on view until August 12. Samantha Friedman, associate curator in the MoMA Department of Drawings and Prints, discusses the show.
