The Frick Collection, one of my favorite places on earth, has a strict no photos policy and their staff should work for Homeland Security because not much gets by them. I was able to sneak a few however unfortunately none of the beautiful exhibit  Pierre Gouthière: Virtuoso Gilder at the French Court- running November 16, 2016 to February 19, 2017. I hope you have a chance to visit before it ends. Here are the photos I was able to take of the rest of the museum.
