To commemorate the recent 50th anniversary of the March on Washington, August 28th, 1963, the Library of Congress has selected these images from its extensive Prints and Photographs collections. Images by members of the White House News Photographers Association, color slides for publication in Look magazine, and pictures from a professional Ohio photographer document a "day that changed the course of history." The online exhibition is organized into sections by photographer. For example, Danny Lyon's "The March on Washington, August, 28, 1963" shows a marcher clapping, while a man next to him snaps his fingers. Roosevelt S. Carter is another photographer worth checking out whose photos include Mahlia Jackson in a truly remarkable hat. For more photos by Carter and others, see the Special Presentation, a slide show that includes a view of a very young Paul Newman with Sammy Davis Jr., color shots of marchers around the reflecting pool, and marchers assembling to take buses and trains to Washington DC.
