Artist's book in the form of loose cardboard sheets in an envelope. Each of the four enclosed cardboard sheets feature six black-and-white photographs, all taken from the same place and acting as coordinates referring to that point. The cardboard sheets can be folded to create three-dimensional sculptures that the artist suggests "may then be raised on thin wood or wire supports so that the four solids are in the proper spacial relationship to each other." Originally from the boxed edition Artists & Photographs.
