Warhol's iconic series of Campbell's Soup Cans paintings were never meant to be celebrated for their form or compositional style, like that of the abstractionists. What made these works significant was Warhol's co-opting of universally recognizable imagery, such as a Campbell's soup can, Mickey Mouse, or the face of Marilyn Monroe, and depicting it as a mass-produced item, but within a fine art context. In that sense, Warhol wasn't just emphasizing popular imagery, but rather providing commentary on how people have come to perceive these things in modern times: as commodities to be bought and sold, identifiable as such with one glance. This early series was hand-painted, but Warhol switched to screenprinting shortly afterwards, favoring the mechanical technique for his mass culture imagery. 100 canvases of campbell's soup cans made up his first solo exhibition at the Ferus Gallery in Los Angeles, and put Warhol on the art world map almost immediately, forever changing the face and content of modern art.
