In the 1930s, when the international Surrealist movement gained prominence, Georgia O’Keeffe was living in New York and visiting New Mexico annually, and Henry Moore was living in the Hampstead section of London. The Surrealists had a huge impact on both artists. O’Keeffe began to create dreamlike paintings; Moore worked on his transformation drawings, in which natural forms morphed into human figures. Both artists studied seashells, bones, river rocks, and plants. In this momentous show, which includes over 120 works, their masterpieces are shown side by side for the first time, and both their studios have been meticulously recreated. —Elena Clavarino
