Like pop art, he has focused on ordinary objects, using repetition and the flattened quality of advertising as a means of structuring the panels. Marco Livingstone's description of Oldenburg's work also fits perfectly with Harper's paintings: "Like the best of Pop, its effect is to awaken us to the strangeness of the ordinary, to present the most routine burdens of our everyday life as almost miraculous appearances. " However, unlike pop art, it is not a critique of capitalism or consumerism. It is not a separate vision of the world. It has replaced the irony for the celebration.
