'It started when I tried to photograph a print by Robert Rauschenberg that was under glass. But the light from a window reflected on the surface of the glass and prevented me from taking a good picture. But it gave me the idea of photographing fairly well-known works under glass, where the reflection would hide most of the work, but you could still make out what the subject was. Well, I tried to do a few photographs in this manner; but I am not much of a photographer. Later the idea occurred to me to do the same idea in painting; and I started this series on various early works of mine … It portrays a painting under glass. It is framed and the glass is preventing you from seeing the painting. Of course the reflections are just an excuse to make an abstract work, with the cartoon image being supposedly partly hidden by the reflections.' —Roy Lichtenstein
