Full description from Andy Warhol museum:

Warhol’s use of the popular everyday product Campbell’s Soup launched his career as a Pop artist. The early 1960s saw the beginning of the pervasive influence of television, instant communications, and instant celebrity. Warhol understood the influential power of advertising and packaging, convincing people to buy all kinds of things. The familiar red-and-white label was immediately recognizable to Americans, and eating Campbell’s Soup was a widely shared experience. Warhol himself said, “Pop art is about liking things,” and claimed that he ate Campbell’s Soup every day for 20 years. This quintessential American product represented modern ideals: it was inexpensive, easily prepared, and available in any food market. Warhol turned to this subject repeatedly throughout his career.
