From petroglyphs to contemporary images in cities, murals continue to tell the stories of people all over the world. Historic struggles for justice, violence and war, or the vitality of youth and neighborhoods, are subject matter for these public art works. Working in creative groups, partnerships, or as individuals, community muralists become the visual storytellers of our time. Community participation can range from identifying key issues important to a neighborhood or group to direct involvement in the fabrication. Contemporary murals are produced in paint, ceramic, metal, and other permanent materials, by hand or in combination with industrial methods and digital technology. Through this creative public process, people are given voice and the opportunity to impact their visual environment.
