Pop Art parodies (or perhaps reflects) a world in which celebrities, brand names, and media images have replaced the sacred; Warhol's series of Campbell's Soup paintings may be the best illustration of this. Like the object itself, the paintings were often done by the mass-producible form of serigraphy (silk screening). Also like the subject, the Warhol soup can painting existed in many varieties, with different types of soup or numbers of cans; painting 32 or 100 or 200 identical cans further emphasized the aspect of mass production in the work. The same approach underlies Warhol's familiar series of prints of Marilyn Monroe, Jacqueline Kennedy Onassis, and other pop culture figures.
