This American edition does not contain the three introductory and one afterword facsimile, pen drawings by John Lennon, which appeared in the Sackner copy of the British edition. Ono documents a performance work, "Breath Piece," as follows: "Breathe. First performed at Wesleyan University, Conn., U.S.A., in 1966. A large card with small lettering saying "breathe" was passed three times among the audience." -- Source of annotation: Marvin or Ruth Sackner.
