Single sheet of wallpaper, printed on lightweight paper, utilizing two stacked images of Yoko Ono's ass. Planned and announced in Fluxusnewpaper, January 31, 1968, and originally credited in collaboration with Ben Vautier and later Robert Watts. Edition was not realized until c. 1973 with copies issued both by Fluxus and Flash Art. As both editions lack attribution they are indistinguishable.
