New York artist Lichtenstein began making paintings inspired by consumer culture as a reaction against the emotional involvement of Abstract Expressionism. He was inspired by comic-strip illustrations, which he enlarged. Although his works may look as if they are made by a machine, Lichtenstein would begin by painting through a perforated metal screen to make the regular pattern of dots, like those used to form areas of colour in magazine pictures. He then painted the solid colour and finally the black outlines. Although he worked in a modern style, the subjects of his work were often traditional, such as portraits, still life, landscapes and genre paintings.
