In my 2017 trip to the USA, I made a stop to admire the The Neustadt Collection of Tiffany lamps, at the Queens Museum, in New York. The collection, assembled by Dr. Egon Neustadt (1898-1984) and his wife Hildegard (1911-1961), features a number of delightful copper foil lamps created by Tiffany Studios right in Queens (in Corona to be exact).
As part of my 2017 trip to the US, I went to visit the Brooklyn Museum. Among other art pieces, the museum features a handful of stained glass panels and some Tiffany lamps (stored in the Visible Archives of the museum).
