The 20th annual Artists of the Wall Festival kicks off at 9 a.m. Saturday, June 15, and lasts until sundown Father's Day. Hundreds of artists will paint murals in sections along the 600-foot-long wall at Loyola Park Beach, 1230 W. Greenleaf Ave.

Although the mural is usually painted over each year, a section of last year's mural that was painted by a slain high school student was preserved in his memory. Organizers plan to add to the mural verses from a poem the student wrote.
