The National Portrait Gallery is a historic art museum between 7th, 9th, F, and G Streets NW in Washington, D.C., in the United States. Founded in 1962 and opened to the public in 1968, it is part of the Smithsonian Institution. Its collections focus on images of famous Americans. The museum is housed in the historic Old Patent Office Building, as is the Smithsonian American Art Museum.
The visualization project explores 150 portraits which are on the physical exhibit from the National Portrait Gallery. It compares the length, width and the area size of each painting separately as well as a whole.
