Yoko Ono - A Portrait of an Avant-Garde Artist is the biography of Yoko Ono, a popular Japanese artist and musician. Ono is known for her work as avant-garde artist and musician, as well as her marriage and works with English musician John Lennon, of Beatles fame. She currently lives in New York City. John Lennon once described her as "the world's most famous unknown artist: everybody knows her name, but nobody knows what she does." Ono first met John Lennon when he visited a preview of an exhibition of Ono's at the Indica Gallery in London on November 9, 1966. Lennon's first personal encounter with Ono involved her passing him a card that read simply "Breathe." He was taken with the positivity, humour, and interactivity of her work. Yoko Ono - A Portrait of an Avant-Garde Artist is highly recommended for those interested in reading more about this talented artist.
