Chicago is home to more intact African American street murals from the 1970s and 1980s than any other U.S. city. Among Chicago's greatest muralists is the legendary William "Bill" Walker (1927-2011), compared by art historians to Diego Rivera. Francis O'Connor, America's foremost mural historian, called Walker the most accomplished contemporary practitioner of the classical mural tradition that runs from Giotto to Rivera.

Though his art could not have been more public, Walker maintained a low profile during his working life and virtually withdrew from the public eye after his retirement in 1989. Author Jeff W. Huebner met Walker in 1990 and embarked on a series of insightful interviews in 2008. Those meetings form the basis of Walls of Prophecy and Protest, the story of Walker's remarkable life and the movement that he inspired.

Featuring thirty-five color images of Walker's work, this handsome edition reveals the artist who was the primary figure behind Chicago's famed Wall of Respect and who created numerous murals that depicted African American historical figures; protested social injustice; and centered imagination, love, respect, and community accountability.
