The original Smithsonian Institution building, known as the Castle, has appeared three times on U.S. postage. A 1946 stamp celebrated the centennial of the Institution, and a 1996 stamp marked the sesquicentennial. This 1980 stamp took a different approach, recognizing the building itself as an American treasure while also honoring the genius of its architect, James Renwick, Jr.
