Roy Lichtenstein was an American pop artist known for his paintings that used cartoon images. Landscapes were one of the first subjects Lichtenstein painted after his breakthrough work incorporating comic imagery. This document discusses Lichtenstein's landscapes, comparing one of his landscape paintings to an earlier landscape work from 1826, and providing information on techniques commonly used in landscape art such as relative size of objects, overlapping forms, use of color and space, inclusion of a horizon line and sky, and incorporating weather elements. It notes that Lichtenstein found inspiration for his landscapes from backgrounds in cartoons rather than directly from nature.
