In the late 1950s and early 1960s, Kirchherr and her art school friends were involved in the European existentialist movement whose followers were later nicknamed "Exis" by Lennon. In 1995, she told BBC Radio Merseyside: "Our philosophy then, because we were only little kids, was wearing black clothes and going around looking moody. Of course, we had a clue who Jean-Paul Sartre was. We got inspired by all the French artists and writers, because that was the closest we could get. England was so far away, and America was out of the question. So France was the nearest. So we got all the information from France, and we tried to dress like the French existentialists... We wanted to be free, we wanted to be different, and tried to be cool, as we call it now."
