Both Andy Warhol and Marilyn Monroe. Andy for being pretty much the best pop artist ever, and Marilyn for having some of the most perfect quotes ever (personally don't care for her acting. She played alot of dun=mb blonde roles)
Andy Warhol's numerous "Dollar Sign" paintings bluntly reminded people that "big time art is big time money", as well as the overall obsession with money. These paintings are symbolic of the greediness and materialism of the entire decade.
