Pontella Mason is one of Baltimore’s unsung visual artists. He has created murals for the Anacostia Community Museum, former President Jimmy Carter, and several other public organisations. His murals depict African American life and the diaspora. In 1999, he created the extensive mural Ancestral Roots, which depicts the antislavery heroes Harriet Tubman, Sojourner Truth, and Frederick Douglass, as well as Martin Luther King Jr., Malcolm X, Muhammad Ali, Notorious B.I.G., Tupac, Shirley Chisholm, and Marcus Garvey.
In 1991, a group of artists – Eddie Orr, David Mosley, William T. Stubbs, Norman Maxwell and Michael McKenzie – collaborated to paint “Black Seeds” on an empty wall in Leslie N. Shaw Park on Jefferson and 3rd Avenue in Los Angeles. The idea for the mural, which appears as an African American tree of life, came from Vietnam veteran and local activist Gus Harris Jr. He recalled how little he learned about African American history in school. He wanted to create a public mural about black individuals who made an important contribution to society.The mural was created under the Social and Public Art Resource Center's 1990-91 “Neigborhood Pride: Great Walls Unlimited” mural program and features the antislavery leaders Harriet Tubman and Frederick Douglass, as well as Booker T. Washington, Thurgood Marshall, Mary McLeod Bethune, Malcolm X, George Washington Carver, Paul Robeson, Stevie Wonder, Shirley Chisholm, Martin Luther King Jr., and Jesse Jackson. The mural was restored by Moses X. Ball to include Barack Obama after 2008. The original canvas upon which the mural was based hangs in Oaks Jr. Market Corner Store at 5th and Jefferson.
