Braque first came upon lithography in 1921. The medium fascinated him as it was less demanding as a technique than etching. Lithography was also more alike to painting, especially in its chromatic possibilities. Despite their similarities, Braque did not copy his lithographs after his paintings. Instead, he chose to only extract the subject matter and the format from his paintings. His most dedicated period to lithograph lasted from 1945 to the end of his life. His later lithographs showcase deliberately thick strokes which tended towards visual intensity rather than accuracy. For some of his lithographs in the Lettera Amorosa, 1963 suite, as many as 13 colors were layered in succession.
