Why do you think it helps the neighborhood and the painter to see Jimmy Lyons represented on the wall?

In "The War of the Wall," by Toni Cade Bambara, the narrator and her cousin, Lou, notice that there's a stranger from out of town attempting to paint a wall in the neighborhood. The narrator feels that the wall belonged to the people in their community and that the painter "had no right" to paint it. Most importantly, chiseled into the wall is the name of Jimmy Lyons. He was a member of the community that went to Vietnam and never returned.
Once the project is completed, the people of the neighborhood have something of which they can be proud. The painter has created a colorful mural to pay tribute to Civil Rights activists and to members of the community. Through her art, the painter is offering the people a sense of pride in their heritage and community. This "Wall of Respect" also contains an inscription in which the painter dedicates her work to her cousin, Jimmy Lyons. Her tribute to her cousin may also serve as an act of healing for the loss she has suffered when he did not return from Vietnam. For these reasons, both the neighborhood and the painter receive benefit from the mural.
