On January 16, 2008, the "three-deep" Colbert portrait was placed on display "right between the bathrooms near the 'America's Presidents' exhibit" at the National Portrait Gallery in Washington, DC.[19] After first being rejected by the National Museum of American History, Colbert petitioned the Smithsonian to display his portrait, who agreed to "go along with the joke", though they stressed that it was only temporary. Colbert said "I don't mean to brag, but as it contains three portraits, my portrait has more portraits than any other portrait in the National Portrait Gallery!" The portrait was then put on display at the Smithsonian until April 13. On October 16, 2008, the three-deep portrait was officially donated to the permanent collection of the Smithsonian's American Treasures exhibit. In September 2009, the portrait was retired to the Smithsonian's collection. At the end of that show, a new 5-deep portrait was unveiled, with the newest Colbert holding his newly won Primetime Emmy Award with another Primetime Emmy Award and a Peabody by the mantle.

Club, Colbert explained that much of the design for the set was inspired by Leonardo da Vinci's The Last Supper. "All the architecture of that room points at Jesus' head, the entire room is a halo", Colbert said. "On the set, I'd like the lines of the set to converge on my head. And so if you look at the design, it all does, it all points at my head...there's a sort of sun-god burst quality about the set around me."[2] On the floor to the front stage right of his desk there is an eagle's nest, and a tape outline of where he injured his wrist, akin to those seen at murder scenes o
