We are trying to id a lovely glass loon with no signature or other identifiers. The family myth is that my mother-in-law and her mother were walking down Fifth Avenue and spotted it in the Tiffany window. My mother-in-law liked it so her mother walked in a bought it for her as a gift. It measures approximately 8" x 9" and is characterized by having deep green interior 'innards' visible through the clear satin glass body to vibrant green visibility on the underside of the beak. The head was painted black. and is now somewhat mottled with clear glass showing through.
Any help with the identification of the artists, or manufacturer would be much appreciated.
