Lichtenstein excerpted an image from a comic book, a form of entertainment meant to be read and discarded, and immortalized the image on a large canvas. Aside from that modification, Lichtenstein remained remarkably faithful to the original comic strip image. His subject was one of the melodramatic scenes common to popular romance comic books of the time. Lichtenstein also used the visual vocabulary of the comic strip, with its dark black outlines and unmodulated color areas, and retained the familiar square dimensions. Moreover, his printing technique, benday dots, called attention to the mass-produced derivation of the image. Named after its inventor, the newspaper printer Benjamin Day, the benday dot system involves the modulation of colors through the placement and size of colored dots. Lichtenstein thus transferred the visual shorthand language of the comic book to the realm of monumental painting.
