The Clinton Presidential Center opens a new exhibit Saturday, Aug. 10: “And Freedom for All: the March on Washington for Jobs and Freedom,” photographs by Stanley Tretick of the 1963 march at which the Rev. Martin Luther King Jr. delivered his "I Have a Dream" speech." Tretick, known for his photographs of the Kennedy White House (including the one of John John under the president's desk), was hired by Look magazine to make behind-the-scenes photos of the march. They were published for the first time this year by the Smithsonian.
The exhibition runs through Nov. 17; you can see it for free Aug. 17, President Clinton's birthday, which the library celebrates by charging no admission.
