I discovered on the Library of Congress website a bit of film made by Thomas Edison. It records a college football game, Princeton vs. Yale, taken in November 1903. http://memory.loc.gov/cgi-bin/query/r?ammem/papr:@filreq(@field(NUMBER+@band(awal+2164))+@field(COLLID+workleis))
Jack "the kid" de Saulles had just graduated Yale the year before. In this year (1903) he was coaching football at the University of Virginia and contributing chapters to Walter Camp's instructional manuals. But even if Jack isn't in this film, it still gives you a good idea of how he would have looked on the field.
