Signed book: Grapefruit. First Sphere Books edition. London: Sphere Books, 1971. Softcover, 5 x 5. Signed on the first free end page in black felt tip by John Lennon and in blue felt tip by Yoko Ono. A Polaroid photo of Lennon taken at the time of signing is removably mounted to the inside of the front cover. In fine condition. Accompanied by a certificate of authenticity from Beatles expert Frank Caiazzo, who notes that the "book was signed on July 15, 1971, at a book signing attended by John and Yoko, at Selfridge's book store in London." A sought-after dual-signed book with great cult appeal, the cover of this uncommon Sphere edition integrates the cheeky subject matter of Ono's 1966 short film Bottoms.Format: Book
