In 1962, artist Andy Warhol took the familiar look of the Campbell’s soup can and integrated it into a series of pop art silkscreens, a theme he would return to off and on through the 1960s and 1970s. The first batch in 1962 were a series of 32 canvases. At first, the cans were accurate representations of actual Campbell’s cans, but as his series progressed, they became more surrealistic, with Warhol experimenting with negative-reversed color schemes and other varied techniques (many of these which would be used on other Warhol paintings of the period, such as his celebrity silkscreens of the 1960s). The silkscreens themselves have become iconic pieces of pop art, with one in particular, Small Torn Campbell Soup Can (Pepper Pot) (1962), commanding a price of $11. 8 million at auction in 2006.
