This National Film Unit production records the making of four large-scale sculptures for a 1971 international symposium to commemorate Auckland City’s centennial. Helen Escobedo (Mexico) nodded to the skyline’s masts and cranes with Signals in Parnell Rose Garden; Opened Stone by Hiroaki Ueda (Japan) was balanced near Auckland Art Gallery for 35 years; and American Fred Loopstra's Homage to Will still ploughs Victoria Park. A central city scrap metal work by Canadian Tom Burrows was removed in 1977, perhaps achieving his stated aim: to “disturb” its viewers!
If they at least stop, and not be able to accept it and let it disturb them in some way then possibly I’ve got through.– Canadian sculptor Tom Burrows
