Campbell Robertson ended up doing three pieces that the Times chopped up and put on their website as slideshows:
"Primary Pen & Ink: Asheville, N.C.," April 30 2008
"Primary Pen & Ink: Whiteville, N.C.," May 2 2008
"Primary Pen & Ink: Raleigh, N.C.," May 5 2008
These weren't too big and were nice pieces of cartoon journalism - it's too bad the Times couldn't squeeze them into print. Oddly enough, at this point I think the Times has the most mainstream coverage of comic art. Including their animation reviews, it's almost daily.
And thanks to PW Comics Week, here's an interview with him:
"Campbell Robertson, Sometimes Cartoonist; The New York Times does non-fiction, political, comics," by Clint Hendler, Columbia Journalism Review Fri 9 May 2008. And serendipity strikes! Robertson went to school in DC! "I did some cartooning in college. I did some stuff for the college paper, the Georgetown Hoya, but very little. I was an English major, and my thesis—and maybe this reflects badly on Georgetown—was a fiction comic book. But I hear they’re still accredited."
It's ComicsDC territory after all...
Here's the earlier article referenced in the CJR: "Yes, But Where's the Nut Graf? The New York Times does comics -- for a day, at least," By Robin Sloan, November 19 2003 and the first NYT piece on a paparazzo from November 2003.
