My husband and I visited the NY Historical society today. We highly recommend it. It's easily accessed by subway, and right across from Central Park. We spent close to 3 hours and there is so much to see we couldn't cover it all. Must sees, in no particular order, are the gallery of Tiffany lamps, Kay Walking Stick /Hudson River School, Acts of Faith and the American West, Enchanting Imagination: The Objets d’Art of André Chervin and Carvin French Jewelers and Women's Work. There's lots more, but we couldn't stay longer and are sure we'll be back.
