Dennis Oppenhiem
Dennis Oppenhiem was a highly prolific artist whose art ranged from performance and film to earthworks and public sculpture. When Oppenhiem did the residency at Artpark in 1975 he sprayed hot tar in the shape of his thumb print and that of his son; it was titled Identity Stretch and it measured more than three football fields in length.
