Rebecca Moses is a woman of many parts: a consummate New Yorker; for 20 years, a resident of a remote Italian village; a fashion designer; and an artist delighting in women and in depicting her subjects as delightful. So it makes sense that her latest endeavor, “Thank You Mount Sinai Nurses”—a traveling exhibition comprising 46 portraits of female members of the multicampus New York hospital’s various nursing teams—is characterized by extraordinary diversity and inclusiveness of vision.
