Until i flipped through the pages of the New Yorker magazine today and found his picture. Didn't care about resemblance here -- just wanted to find a quiet hour at the public library, draw, and clear my head. 2B pencil on Canson sketch paper.
Driving down to Philadelphia, i got stuck in bumper-to-bumper traffic behind this truck on the NJ turnpike. I drew it while shifting between first and second gear, which killed some time. I was at the wheel -- hence the blind contour-esque aspect. :-)
