John Lennon made drawings before he met Yoko Ono in 1966, but it was only after he started a relationship with Ono—at the time a rising art star—that he really came into his own as an artist. Over the course of their time together, the Beatle went from rendering cartoons influenced by British absurdist humor to a simple but elegant style that was indebted to both contemporary minimalism and traditional Japanese painting. His modest, intimate portraits of Yoko and their son Sean provided a fitting visual accompaniment to the music he made about their lives together.
