Lastly I was thinking about some of my favorite grids and copies without originals by Félix González-Torres. Especially his piles of paper that the public can take from as they like and are infinitely replenished by the museum or gallery. I wonder if they are editioned… I know his piece Perfect Lovers is editioned as three plus one artist proof but this one hanging in the office of the Renaissance Society is rumored to be an authorized exhibition copy. Also anyone with two matching clocks can have a pretty amazing forgery of this piece.
