Look at this great picture:
Providence, R.I., 3/1/2008
From the photographer, Callie Shell:
Senator Obama was doing press interviews by telephone in a holding room between events. Sometime later as he was getting ready to begin his event, he asked me if I was photographing his shoes. When I said yes, he told me that he had already had them resoled once since he entered the race a year earlier."

This one brought tears to my eyes:

Jan. 21, 2008
From Callie Shell:
These two boys waited as a long line of adults greeted Senator Obama before a rally on Martin Luther King Day in Columbia, S.C. They never took their eyes off of him. Their grandmother told me, "Our young men have waited a long time to have someone to look up to, to make them believe Dr. King's words can be true for them."
Just look at their sweet faces.
