Today we’re taking a look at a signed, second edition copy of Grapefruit, Yoko Ono’s pioneering work of conceptual art. Yoko Ono was a fixture of the subversive 1960’s New York underground art scene, and is most associated with the Dada-inspired Fluxus movement. First published in 1964, Grapefruit consists of a series of “event scores”, poetic, zen-influenced performance scripts that can be followed by anyone to create musical or artistic pieces. This particular copy is also signed by Ono’s husband at the time, John Lennon, who wrote the introduction to this edition and was a popular musician in his own right.
