Crying Girl continues a mechanical reproduction of art, which Lichtenstein and Warhol made a significant part of the Pop Art movement. This particular artwork was an enamel-on-steel piece, a development onwards from previous comic strip portraits on canvas. The content used by Lichtenstein was fresh in the 1960s, and manages to retain that feeling of contemporary style, even today. Fashion, commerce and advertising were huge influences on the Pop Art movement, and much of Lichtenstein's work could be used as posters themselves. His clear lines and dotted forms were in line with the printing press but with his own artistic touch and handmade paintings, they became something more.
