NEW YORK (AP) _ ``The Colbert Report'' celebrated its one-year anniversary Tuesday by offering the show's devoted audience _ the ``Colbert Nation'' _ a piece of its leader.

Colbert announced that he will auction the portrait that hangs above the fireplace on the set of his Comedy Central show. The painting depicts a debonair Colbert standing in front of the very same portrait of himself.

The portrait will be auctioned on eBay until Oct. 30, with proceeds to benefit Save the Children.

``I've already saved the world. How hard could saving the children be?'' Colbert said in a statement.

The effect of the painting is that of a hall of mirrors _ not unlike the strange reflections of Colbert's comedy, which bounces back and forth between reality and truthiness. A spinoff of ``The Daily Show,'' ``The Colbert Report'' has built a following of its own since debuting last year, when it famously coined ``truthiness'' as truth that comes from the gut, not books.

The ``Colbert Report,'' a deadpan parody of combative, conservative talk shows, also recently wrapped up its ``Green Screen Challenge,'' in which viewers were urged to supply new video background to footage of Colbert fighting with a lightsaber.

A video by a viewer identified as Bonnie R. trumped a late entry from _ as Colbert introduced _ George L. It turned out to be the work of ``Star Wars'' director George Lucas, who appeared on the program last week.

``The Colbert Report'' airs Mondays through Thursdays at 11:30 p.m. ET.
