Nose art personalizes a plane for its crew, because it is the crew members who name the plane and create the art, imbuing the plane with an identity of its own. Although some examples of nonregulation art can be found on the military aircraft of other English-speaking countries, the phenomenon is predominantly American, perhaps due to the streak of rebellious individualism attributed to American culture. Nose art is important as an historical and societal indicator over time, an example of folk art or popular expression, and a record of the past.
