In 1989 the Guatemalan Information Center, a human rights organization, commissioned Mark Vallen to create this poster. Its purpose was to announce the Guatemalan Human Rights Tribunal, a public forum held in Los Angeles
City Hall on the subject of the war then raging in Guatemala. At the tribunal eyewitness accounts of the war were provided. The original artwork was a chalk pastel drawing that measured 3 x 5 feet. The chalk drawing was printed as the full-color, 11 x 15 inch offset poster.
