The “Masterpiece-Happening Archive” Project by curator Suely Rolnik presents her interviews made with 20 related personalities to discuss and register the proposals of artist Lygia Clark and the legacy left by her research, which is situated in the boundaries between art and therapy. The interviews generated a 20-DVD box. The design of the Box is a miniature adaptation of a piece of furniture with hanging archives. Each DVD is found at a small archive-file inside the box. The choice for such retro object was due to the fact that its design coincides with the period focused by the research, namely the 60's and 70's.The information presented by the graphic material take up the shape of cartographies as to make clear the relations between the diverse project actors as well as to potentiate the perception that the quoted happenings go beyond a given work of art, epoch, or specific person.
