In 1962, Andy Warhol started a series of silkscreened paintings of death and disasters that included photographs of suicides, plane and car crashes, and tragedy-stricken celebrities such as Marilyn Monroe and Jacqueline Kennedy. All the images were taken from the print media. He depicted an electric chair in several groups of silk-screens throughout the 1960s, the first in 1963--the same year that New York's Sing Sing State Penetentiary performed its last two executions by electric chair (capital punishment was banned in the United States from 1963-1997). For his 1968 retrospective at the Moderna Museet in Stockholm, Warhol produced yet another series, of which these works are a part. In these prints, however, he made some variations: he cropped the image to bring the electric chair to the foreground, and screened it in a variety of colors other than black, occasionally printing off-register double images. By the artist's account, the replication of the image was intended to "empty" it of meaning.
