Excerpt:

While this triple portrait is not one that would typically be accessioned into the portrait gallery’s permanent collection, NPG agreed to go along with the joke and hang the portrait for a limited time. In episodes of The Colbert Report that aired on January 10, 14, and 15, 2008, Colbert tries to convince the Smithsonian that he should be considered a national treasure. He attempts to donate his portrait to the Smithsonian’s National Museum of American History, but the museum’s director suggests that perhaps Colbert should speak to the National Portrait Gallery. Finally, after much “discussion,” the director of the National Portrait Gallery finds an appropriate place to hang Colbert’s portrait, in between the bathrooms and above the water fountain.
