Rain goes commercial

This is not related to Dae Jang Geum but interesting none the less. It seems that Rain's commercial success has epitomized itsef in the form of a jumbo jet. There are plenty of singers and actors in America and across the globe that have their own jets, but I cannot think of any that have their own portraits painted on the plane. Even American hip-hop stars who seem to take eveything the nth degree have not tried anything like this to my knowledge. Is this simply an over the top marketing tool for Rain or can we think of it as a defining moment for Korean Pop culture in general. Its certainly not the same as a billboard or concert in New York City because it is much more mobile.
