The must-see exhibit in Paris this winter is a freebie at the Hôtel de Ville dedicated to 150 photos of Paris by the prestigious members of the Magnum agency. Paris Magnum, la retrospective (par-ee man-yum lah ret-ro-spek-teev) is open from December 11, 2014 until March 28, 2015. See famous photos by Depardon, Parr, or Cartier-Bresson. For this exhibit, City Hall asked Magnum to sort through 80 years of photos in its archives for the most remarkable photographs of the changing face of Paris. Think about photos of the May 1968 juxtaposed with the arrival of the mini-skirt. It’s open from 10 am to 7 pm every day except Sunday.
