Most of the observers in war are writers, photographers, or videographers, but there have been a few artists on the front lines of combat in recent years, and one of them is Steve Mumford.
He says he is not a "war junky," but rather an artist first and foremost, like Winslow Homer, whose war art was just a part of his overall output.
Many of his paintings are done on location, but he also works in the studio from photos and from his quicker sketches done on the spot. These are typically drawn in sepia line and wash.
