My wife and I went to the Columbia Museum of Art for a Norman Rockwell exhibition. I was not aware how he used photography on a regular basis to create some of his magazine covers. Also, after his time at the Saturday Evening Post, he took on more controversial topics by using themes from the Civil Rights movement. The picture below, "The Problem We all Live With" shows a young girl being escorted to school by U.S. Marshalls. The girl is the problem; the problem is that she needs federal protection to attend school.
Here is a link to the exhibit itself:
