A barn advertisement is an outdoor advertisement painted onto the exterior of a roadside barn. Advertisers take advantage of the barns' prominence in rural landscapes, paying their owners for the right to paint and maintain logos and slogans on them.[1] Painters of barn advertisements and other murals are known as "wall dogs".[2] Once a common form of billboard advertising in the Midwestern and Southeastern United States during the early– to mid–20th century, barn advertisements have faded into obscurity, as many of these rural ghost signs fall into disrepair, along with the structures that bear them.[3]
