The Veterans Room of the Park Avenue Armory was used as the interior of Commodore’s house in the first two seasons. Louis Comfort Tiffany was hired as the primary designer of the Veterans Club Room when he was 32 years of age, and had not yet made his famous Tiffany Lamps. Instead, he was known as a landscape painter. He hired a young Stanford White to act as consulting architect, and their commission of the Veterans Room went so well that they were then commissioned to do the adjacent Library. The Veterans Room is one of the few surviving interior spaces in the entire world created by Tiffany and other prominent artisans associated with this project.
