Series I. Poster projects presents in chronological order their notorious posters detailing discrimination against women artists. Series II. Assorted graphic work, shows their assiduous pursuit of justice through mass and individual mailings about and to various art world figures, such as critics, dealers, and curators, along with the private replies they often received. This series also provides a glimpse into their collective compositional process, with drafts of posters and comments on them, along with source material in the form of clippings and statistical reports. Series III. Publications concerns books and serials they created. Series IV. Photographs, V. Exhibitions, and VI.
