Because my article will analyze the relationship between contemporary art and obsolete printing technology, please analyze a few famous contemporary trendy artists in my article, for example, Hajime Sorayama, Murakami Takashi, Kenny Wong, Keith Haring, James Jean, etc. Since there is no precise answer to the concept of contemporary art, I think the definition of contemporary art is ART + pop culture + fashion + media + life + affordable + illustration. It is not just pop art. [Please include illustrations
