The painting shown, is called "sunrise" because that's exactly what it is. With Lichtenstein he just calls it what he see's it, which makes him different from the others. He doesn't allow others to knock him down, because he knows what he is doing is his own. Bringing in pop art to a culture that has always been strictly classical, was not an easy task. But Lichtenstein was able to do it on his own, and that's what makes him unique.
