This is what I was working on last night, a caricature of Keith Oberman for the New Yorker. In the first he's yelling out of his fourth floor Rockefeller Center office (shades of "Network") and in the second he's posing like Edward R. Murrow with a giant microphone. In the end we combined the two sketches and revved up Olberman's pose into something more manic. Then I did a watercolor final, emailed it and went to bed, before dawn even.
Both of these are fast ink sketches on semi-translucent paper, so I can slipsheet them and rework them by semi-tracing. It's my favorite way to work, fast and dirty, and I wish I could always work like this.
