Nose Art is a decorative painting or design on the fuselage of an aircraft, usually chalked up on the front fuselage, and is a form of aircraft graffiti.
While begun for practical reasons of identifying friendly units, the practice evolved to express the individuality often constrained by the uniformity of the military, to evoke memories of home and peacetime life, and as a kind of psychological protection against the stresses of war and the probability of death. The appeal,… in part, came from nose art not being officially approved, even when the regulations against it were not enforced.
Because of its individual and unofficial nature, it is considered folk art, inseparable from work as well as representative of a group. It can also be compared to sophisticated graffiti. In both cases, the artist is often anonymous, and the art itself is ephemeral. In addition, it relies on materials immediately available.
