Aircraft Nose Art
Nose art is a decorative painting or design on the fuselage of a military aircraft, usually located near the nose, 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.
Mostly, various girls are the subject of the nose art.
Animals like tiger, dragon and eagle are also popular
And other kind of texture, flower, cartoon figure..
