About THE NEUSTADT COLLECTION OF TIFFANY GLASS

The Neustadt Collection of Tiffany Glass is an independent 501(c)(3) museum and foundation based in Long Island City, NY, that preserves and exhibits one of the world’s most comprehensive assemblies of Louis C. Tiffany’s glass, lamps, windows, and related materials. It maintains a unique Tiffany Glass Archive (nearly half a million pieces of original Tiffany flat glass and pressed-glass “jewels”), operates a dedicated gallery at the Queens Museum, and organizes a robust national traveling-exhibition program. In recent years the Neustadt has remained active in loaning objects and mounting traveling exhibitions (including programs and installations presented in 2023–2025), developing new scholarship, and offering curator-led archive tours and virtual programs. The organization files as a private foundation (Form 990-PF) and continues to steward its collection, conserve objects for travel and display, and expand public access through partnerships with museums and cultural institutions.
