Andy Warhol pioneered Pop Art, appropriating imagery and objects from popular culture, including references to celebrities and consumer products. In Hammer and Sickle, Warhol works with an icon of communist ideology; the hammer and the sickle together stand for the solidarity of the working class and the peasants. During a trip to Italy, the artist became fascinated by the recurrence of the hammer and sickle in graffiti. Unsatisfied with reference images of the political symbol, Warhol purchased a hammer and a sickle from a New York hardware store and proceeded to sign the tools and photograph them. Warhol claimed an apolitical stance in his work, but his approach to this communist icon as an image from popular culture was deeply provocative—particularly in the tense Cold War atmosphere of the 1970s.
