Yoko Ono is a Japanese artist, who was part of the Conceptual Art movement. A lot of her work is trying spread a message about world peace. Not all of her art was produced on paper and canvas, she spread her art and message through visual performances and musical compositions. However the majority of her pieces are photography work. Many of her paper drawings were created using ink on paper. One of her popular pieces was creatively splattering red pigment onto a pair of bronze high heeled shoes. Ono is associated with the Fluxus group, it's founder who is George Maciunas is Ono's friend and promoted her work and presented it at his gallery in 1961. Another one of her famous pieces is a book she produced which is titled 'Grapefruit' which was published in 1964. The book isn't filled with art pieces, but rather sets of instructions. This allows the reader to produce a piece of solid artwork on material themselves or simply visualize the art Ono created through words. (Artist website) Read Less
