Dora Maar was immortalized as the “Weeping Woman,” but a new show of the Surrealist photographer’s rare photograms and never-before-seen images highlight her independent artistic achievements beyond her association with Picasso. The show coincides with renewed interest in her legacy, including Louisa Treger’s book The Paris Muse (Bloomsbury) and a play called Maar, Dora at Camden Fringe that emphasizes her significant yet often overshadowed artistic contributions.
