In 1965, Lichtenstein began working on the Brushstroke Series. His inspiration was a comic book cell, done by Dick Giordano. Giordano's work depicted an artist who emotionally drained after completing a painting. Lichtenstien's first Brushstroke painting was very similar to the work of Giordano but Lichtenstien continued to use the brushstroke in varying ways for the rest of his career.
Roy Lichtenstein was inducted into the US Army and sent to England just before Christmas in 1944. Although his induction interrupted his studies at the Art Students League, Lichtenstein’s time in London had a profound influence on his work.
