From This American Life Website:
In early 2010, we heard that a writer working for Marvel named James Asmus was a fan of This American Life, and had included a passing mention to our show in an X-Men comic book. It ended up being Nation X #1, with the panel in question (drawn by artist Michael Allred, colored by Laura Allred) depicting the characters Wolverine and Nightcrawler listening to This American Life while driving across the country in a pickup truck. So we thought, why not turn the thing into a poster? The fine folks over at Marvel agreed to collaborate, and we came up with this handsome 16" x 32" enlargement. The initial run is a limited edition of just 2000 posters. Supernerds rejoice!
