The Cylinder is on tour in the US and will be at other museums in other cities. The website has more information here. What surprised me is just how small the Cylinder is (I did not see the website in advance) -- it’s shape and size reminded me of the pressed-wood logs we use in the fireplace in the winter. It makes the discovery even more impressive.
A few small tips for visiting the Met, which you may know already: Do not be put off by the suggested admission price. If you can afford $25 a person, good for you. If not, go anyway. Plenty of people just give what they can and the admissions desk will give you no grief. It’s worth the trip. Also, try to get there early because especially on weekends, the museum gets plenty crowded. Finally, do not attempt to bring a picnic lunch into the museum with you. The guards are very strict about allowing food inside. Your best bet is to check your bag when you enter and then go out to the park and eat there.
