In 1969, he began to explore them in detail. In analogy to his first Pop Art pictures which had been reproductions of comic strip images, his Mirror Paintings were based on catalogues, ads and pictures from the yellow pages. Lichtenstein was not interested in the sharp reflection of reality in a mirror, but with the reflection which seems to lift of the materiality of the reflected objects. His still life works such as the Still Life with Glass and Peeled Lemon from 1972 build another segment of the exhibition. He combined the compositions of the Dutch masters of the 17th century with the precision of the American trompe-l'oeil masters such as William M. Harnett.
Surrealism is another part of Lichtenstein's cosmos.
Since 1982, Lichtenstein began to put together motifs from two different pictures. Since about 1985, he worked on his Reflections which are put in stripes over pre-existing motifs. Below, you can see Reflections on Interior with Gril Drawing from 1990, which clearly plays with Picasso's iconography and cubism. In fact, the work below is based on a painting by Picasso on display at the Museum of Modern Art in New York. Lichtenstein kept the basic arrangement of figure and objects, but added the elements of reflections as well as the frame.
