There are Origami kits available at MMOA. There however is not a fixed exhibit. The American Museum of Natural History has a Christmas Tree decorated with origami ornaments.
No
Not sure about your question.... does the museum teach it? They don't, unless its a special occasion. Do they sell origami paper? I don't think so. Is there origami on display? Perhaps for a special occasion, but I've never seen it in their permanent galleries
