Nina Leen, one of the first female photographers to work for Life, took pictures for the magazine from 1940 to 1972. In the mid-1940s, her essay, “City Dogs”, featured actors and artists with their pets on the streets of New York City. In late-March, Daniel Cooney Fine Art in New York City, is opening a solo exhibition of Leen’s work that features images from that essay and others.
