The following information is NOT printed on this postcard: A billboard is a large outdoor advertising structure, typically found in high traffic areas such as alongside busy roads. Billboards present large advertisements to passing pedestrians and drivers. Typically showing large, ostensibly witty slogans, and distinctive visuals, billboards are highly visible. Many groups such as Scenic America have complained that billboards on highways cause excessive clearing of trees and intrude on the surrounding landscape, with billboards' bright colors, lights and large fonts making it difficult to focus on anything else, making them a form of visual pollution. Other groups believe that billboards and advertising in general contribute negatively to the mental climate of a culture by promoting products as providing feelings of completeness, wellness and popularity to motivate purchase. One focal point for this sentiment would be the magazine AdBusters, which will often showcase politically motivated billboard and other advertising vandalism, called culture jamming. When a well-done billboard graffiti is photographed and produced as a postcard, it can reach many more people with its alternative message.
