Eva Lemon’s (left) small, black patent leather school shoes clack against the warm sidewalk, her stride in sync with Martin Luther King Jr. and her classmate Aretha as they push through a crowd of supporters and segregationists. Before they arrive at the school steps, a quick click of Bob Fitch’s camera captures the moment Lemon became King’s ‘Poster Child.’ Photo by Bob Fitch/Stanford University Libraries Department of Special Collections
