Although sharing an address with the famous Wall of Respect, the Wall of Truth was different. Whilst the Wall of Respect exalted black role models, leaders and liberators, the Wall of Truth wove negative scenes of poverty, brutality and racism into the fabric of the urban environment. Rather than promoting racial pride, it highlighted racial disparities. “The intent on the opposite side [of the road] was that things had gone more militant,” muralist Eugene Wade explained: “more blackness was needed in terms of representing the Black Power symbol and the whole thrust of what was happening in the black community.” Wade notes that “people were getting angry and fed up, so what we were trying to do was implement the attitude and the mood."The Wall of Truth was a significantly larger mural than its Chicago neighbour, the Wall of Respect. It spanned the length of an apartment building, and wrapped around onto an adjoining wall. It contained nine separate narrative panels and was one of the first instances that a radical black past was visualised in the streets through the antislavery leaders Frederick Douglass and Nathaniel Turner, as well as Mary McLeod Bethune, W.E.B. Du Bois, H. Rap Brown, Stokely Carmichael, Marcus Garvey, Huey P. Newton, Fred Hampton, and Malcolm X.

In 1972, a pioneer of the Chicago mural movement, William Walker, painted a mural on Strangers Home Missionary Baptist Church that was both a rallying call for social justice and a symbol of love and unity. Painted in an era of social revolution, and radical in its day, the inclusionary mural incorporated the names of individuals such as Jesus, Gandhi, Malcolm X, Martin Luther King Jr., and Anne Frank. Further down the murals are the martyrs of the Civil Rights and Black Power movements – names such as Medgar Evers, Mrs. Liuzzo, Fred Hampton, Mark Clark and Emmett Till. In December 2015, All of Mankind was suddenly destroyed. Jon Pounds, executive director of the Chicago Public Art Group (formerly known as the Chicago Mural Group), commented that the mural was a rare remnant of the civil rights era. He knew it was under threat when the church went up for sale in 2011, but preservationists had tried to protect the mural.
