I went to the corbis website and did an image search for kERRY NIXON (little k, the rest all caps). It turned up 1 photo, and it's the one with kerry watching Nixon on tv. If you click the photo, it brings up another screen with a larger image of the photo, caption, and some other stuff. It says the photos was taken January 24, 1973 in Lowell, Massachusetts. It identifies him as a Vietnam vet and head of Vietnam Veterans Against the War.
Thanks y'all...that is the photo! He was representing himself as the head of VVAW as late as 1973. I probably could have found it if I was able to look a little more...someone tried to break in our office yesterday morning, so I was dealing with the police, glass contractors and such all day. Thanks again, I will bookmark this for next time I need it.
