The Sgt shooting the Viet Cong in the street. The green eyed woman from Africa during famine. The GI kissing his girl during the homecoming parade. Martin Luther King being arrested, and/or speaking in from of Washington’s memorial in ‘63. The Kennedy kids playing in the oval office while their Dad worked. The Hindenberg burning. Bobby Orr scoring while in mid flight after being checked and sent flying. Einstein riding his bicycle. There are thousands of photos that should be here but are not, and there are several here that certainly should not be recognized as among the 40 most powerful photographs.
