[2] The gallery provided a venue for emerging American and European minimalist and Conceptual artists, among them Bas Jan Ader, Terry Allen, Michael Asher, Daniel Buren, Jan Dibbets, Ger Van Elk, On Kawara, Joseph Kosuth, David Lamelas, William Leavitt, Allan McCollum, Allen Ruppersberg, and William Wegman.
[4][5][6] Copley's invitation to Michael Asher to launch his first American solo show in her space resulted in the work that the gallery may be best known for, the 1974 Installation where Asher removed the separating wall between the exhibition space and the back room storage and office areas.
[7] In addition, Asher intentionally left the walls of the gallery itself completely blank.
By championing artists like Asher, Copley and other gallery owners at the time sought to challenge the reign of market forces by exhibiting works that couldn't be bought or sold.
[9] This stance in no small part led to the closing of the Copley Gallery after only a few years and to Copley's founding, along with Morgan Thomas and Connie Lewallen, of the non-profit Foundation for Art Resources, a non-profit organization dedicated to exhibiting unconventional work in public spaces.
