The exhibit this woman is viewing is "Pit Bull Flower Power" by the French photographer Sophie Gamand.
Sophie is an animal advocate living and working in New York. Since 2010, she has been focusing on dogs and our relationship with them,particularly shelter dogs.
By donating her time and (a little flower power) to animal shelters, Gamand has helped hundreds of dogs find a new home including these pit bulls languishing in shelters where they are most often euthanized.
