32 x 23 x 5cm red cardboard clamshell box content of c. 60 unnumbered and unbound sheets including one object multiple (a plastic bottle with printed label). Silver ribbon. A supposed "exhibition in a box" with reproduced and original contributions by Tinkerbell, Marina Abramovic, Ay-o, Matthew Barney, Tracey Emin, Valie Export, AL Hansen, ALison Knowles, Shigeko Kubota, John Lennon and Yoko Ono, Pieter Mol, Charlotte Moorman and NAm June Paik, Otto Muehl, Orlan, Willem De Ridder, Niki de Saint Phalle, Carolee Schneemann, AndresSerrano, Annie Sprinkle, Ulay, Ben Vautier and others. The plastic bottle (meant to contain sanitiser gel) is by Marco Tiberio. One of 25 "silver" examples which were announced as being numbered but we cannot find any numbering in the box. Near fine.

60 x 60cm, b/w offset print on thick paper. A series of 15 b/w photographs of former porn star but later Fluxus artist Sprinkle taken by Leslie Barany where the artist is manipulating her large breasts into different shapes. One of c. 220 prints made but this is one of a small number which were signed on the reverse in ink by the artist. VG+.

35 x 25cm, 24pp (self cover). A single number of this posthumous tribute to De Ridder with original contributions by Annie Sprinkle, Larry Miller, Ken Friedman, and others. Articles on all parts of his life including his macrobiotics, his art, involvement in Fluxus from the 60s and his publications (such as Screw magazine). Colour and b/w images throughout. A joyful memoriam. VG+.

27.5 x 21.5cm, 216pp. Full colour card covers. First edition of this illustrated (throughout in b/w) auto-biography of the artist and pornstar who explains her interests in sexual activity and liberation and her later conversion to performance and visual artist. Some illustrations are censored when covering her more unusual activities (mainly the "golden showers" that gave her her porn pseudonym - no mother's maiden name allied with her first pet's name here!) but most aren't and many of her artworks are here. Interesting stuff if you aren't too prudish. Fine.
