Titled and signed in English, dated on the reverse. If we go back to 1961 when this work was created, Kusama became famous overnight in New York with her infinity-net works. In 1960, the Stephen Radich Gallery signed a long-term contract to serve as her agent and the following year her infinity-net works were nominated as part of the Whitney Museum of American Art's annual Contemporary American Painting Exhibition, where she and Georgia O'Keeffe were the only two female artists, an indication of the high esteem in which Kusama was already held. It was in this period that Black & Black was completed, in which the artist employed her powerful visual language and minimalistic colours, deducing complexity from simplicity and the most minimalist of colours to create a work rich in references, perfectly showcasing the avant-garde, fearlessness, self-innovation and transcendence of Yayoi Kusama.
