Aaron Rose spent three summers in the early nineteen-sixties photographing the beaches of Coney Island. Shooting inconspicuously with a 35-mm. Leica, Rose caught his subjects unawares, and, in the process, captured the sweaty languor of New York City’s most iconic summer attraction. The exhibition titled In A World of Their Own, is now showing at the Museum of the City of New York.   All images by Aaron Rose, courtesy The Museum of the City of New York.
