Here's an illustration of Abraham Lincoln I did for this week's New York Times Book Review
(AD: Nicholas Blechman). I actually enjoyed this assignment so much that I did 2 different drawings of Abe for the art director to choose from. They ran the more iconic "bearded Abe" above, but you can also see the younger, "clean and fresh" Lincoln below.
One thing I learned drawing these: Abraham Lincoln had great hair.
