Martin still didn't want it, but Colbert is hoping that someone will; he is putting the portrait up for auction at Phillips de Pury with proceeds going to

The portrait goes up for sale on March 8, but can be viewed from February 25 through March 7 at the Phillips de Pury auction house in New York. If you can't make it to New York for the auction, don't fret - Colbert will show footage of the auction on a future episode.
