This is Paul Bond's Lao Tzu's Dream. (Do you know what Lao Tzu's name means? Old Teacher. ) Yeah, I'm a total STAN. Look at how he uses hyper-realism (the stones' texture) but utterly surreal elements...you know, the tree & such...knock the viewer a little off balance. Plus, it's a little mockery of the whole hipster cairn-building fad. He's good.

A great example of a postmodernist artist is an artist named Roy Lichtenstein. His painting called "Whaam!" from 1963 used speech bubbles and onomatopoeia to express itself in the painting. Lichtenstein's work was known to break down and analyze the difference between pop culture and high culture. He heavily uses the ties to postmodernism and intertextuality with the different styles of culture to reflect onto the war and its effects onto society.
