This issue of Studio International contains a 48-page "exhibition" organized by Seth Siegelaub: "The content of the 48-page exhibition in this issue was organized by requesting six critics to each edit an 8-page section of the magazine, and in turn, to make available their section to the artist(s) that interest them. The Table of Contents lists the name of the artist(s) under the name of the critic who was responsible for their participation." -- Seth Siegelaub.
