Cameras replaced most of the artists capturing conflict long ago, but not all. This is a look at the Iraq war, as you never saw it. Few of us venture out beyond the limits of our settle lives.  But artist Steve Mumford paid his own way to war, just to create art.  He bought his own flack jacket, his own airplane ticket and hitched a ride into battle, armed with only a press pass from an online arts magazine.  He spent more than 11 months on the front lines. The world has seen more images from the Iraq war than any other conflict in history.  None like his.
