Newcastle Ale Billboard Shadow Effect Created by 3000 Bottle Caps

Newcastle Shadow Billboard

Artists Ellis Gallagher and Pablo Power affixed 3000 bottle caps to a Newcastle Brown Ale billboard, creating an amazing shadow effect that is only visible at night. The billboard is on display in San Diego’s Gas Lamp district through September 31, 2011. Ad agency Vitro commissioned the billboard.
