Warhol’s Campbell’s Soup Cans consist of thirty-two canvases, one of each of the 32 varieties offered by the company at the time. It is the work of art that led to pop art becoming a major art movement in the USA. The non-painterly style and the commercial subject of the painting initially caused offence as it affronted the technique and philosophy of Abstract Expressionism, the then dominant style in the United States. The resulting debates on the merits and ethics of such work made Andy Warhol the leading and most well-known pop artist.
