This is not an "anti-american" drawing at all. It's about how growing up between different countries/cultures leaves open spaces for the eye/mind to see, and when you voice out such ideas, it can be very badly responded to by people with narrower perspectives. It's about my friend Eun Kyoung Ju's story. Her blog: http://tomatoxorange.blogspot.com/.
About Ana Milisavljevic's story, she wrote an article about her concept of 'home'. Reaction to the illustration: "this is cool because it summarises me in so many ways" :)
