Artist's book published in conjunction with "Acorn Event" held at "Coventry Cathedral on June 15, 1968, in which the couple famously created Acorn Piece, a conceptual sculpture in which acorns were planted facing east and west." (Kevin Concannon "Lost in the Archive: Yoko Ono and John Lennon's Four Thoughts," in Review of Japanese Culture and Society, Vol. 28 (2016), pp. 262-263.) Texts by John Lennon: "This is what happens when two clouds meet," and Yoko Ono: "This is what happens with two clouds meet (the piece is John's idea but it was so good that I stole it)." Additional text by Anthony Fawcett: "The concept of these sculptures by John Lennon and Yoko Ono is expressed by their statement 'this is what happens when two clouds meet'. It is both symbolic and humorous at the same time. The thoughts behind it are beautiful and its true fulfillment through the cycle of growth is an end in itself – the best idea that can ever be conceived as a work of art – Mother nature is supreme, overriding man's artificial constructions. The seeds, although they can not be seen at this stage, are acorns and slowly the oak trees will develop. It covers all fields for them – it's a game, a joke, but at the same time serious, in the idiom of their music, their writings or even. These ideas place them on a different level than other sculptures in the exhibition so they need to be looked at through new eyes. Cry, laugh, or walk into the sky. There will never be another like them." First interior page features well-known image of Lennon and Ono by Keith McMillan. Only one copy is documented in WordCat, held by Tate Library, London.
