Perhaps this topic is particularly on my mind because I have recently returned from a trip through Arkansas, Tennessee, and Mississippi where I had a chance to see some of the places which formed some of the most powerful images of the civil rights movement - Little Rock Central High School, the Lorraine Motel in Memphis, and the Lyceum at Ole Miss. Until the moment I saw those places firsthand, I could only imagine them through written descriptions of what happened there and from the still and moving images of what happened at each of them more than half a century ago. Iconic images which tell a story so much more deeply than the written texts or even on-camera interviews which accompany them. They help connect me to a world before I was born, a world it is sometimes hard to believe existed if not for these images as everlasting evidence.
