Piper, Just a suggestion, but a wonderful place that we once did some work for is the Corning Museum of Glass in Corning New York. They are a private, non-profit museum but have a history of being founded by the Corning Glass company. It is one of the most amazing collections of glass in the country and the world. I no longer have a contact there, but I am sure you could contact their curatorial or development offices and speak with them. I am sure it would be a fine home for your pieces of Tiffany glass.
