Artist's project by Ira Joel Haber, artist and employee of Norbert J. Prager Associates, a company that dealt with mailed surveys. Haber asked 27 artists to check two sets of numbers "to share with them my immediate environment in some of its visual and process forms. I consider this sharing an art work, the second part of which is this explanation, along with the enclosed list of response." Artists asked were Hannah Weiner*, Vito Acconci, Scott Burton, John McSpadden, Lil Picard, Abe Lubelski, Arakawa, Ron Liberman, Marjorie Strider, Lucy Lippard, Eduardo Costa, Rosemary Ceravolo*, Steve Lawrence*, Howard Stabin, Dan Graham, Sol LeWitt, Adrian Piper, Douglas Huebler*, Seth Siegelaub*, Stephan Kaltenbach, Les Levine*, Terry Anderson*, Aram Saroyan, Jack Anderson, Mel Bochner*, and Bernadette Mayer (* indicates they did not respond). Respondents included number of errors found, if any, and their signatures, included in the publication.
