Lichtenstein's art has the capacity to be enjoyed and understood by everyone at least on some level due to the fact that his subject matter was pulled from everyday materials. He used magazine color, a graphic line, and ben-day dots. His paintings were essentially pure, traditional painting, without collage, experimental materials or complicated techniques.
It is in his prints that Lichtenstein experimented with materials. He made his first print, a combination of lithography and woodcut, in 1948 while a graduate student at Ohio State University in Columbus, and added the intaglio processes of etching, engraving and aquatint in 1950. Red Barn follows Lichtenstein's celebrated Haystack and Cathedral Series, what Lichtenstein himself referred to as "manufactured Monet's" of 1969. Between 1969 and 1993, the artist completed more than twenty extended print series, most of which comprise six to eight images.
