The work began as a 14 centimetres (5.5 in) maquette made in plaster in 1969, and then cast in bronze.  An example of the bronze is exhibited by the Henry Moore Foundation in Perry Green.
The maquette was enlarged to a 142 centimetres (56 in) plaster working model in 1971, which was then cast in bronze in an edition of 7+1 (seven casts plus an artist's copy). The plaster model is Perry Green, and examples of the bronze casts are at the Fine Arts Museums of San Francisco and the Hakone Open-Air Museum.The work was enlarged again in 1971-72 to create a full size bronze on a monumental scale, 570 centimetres (220 in) high, in edition of 3+1.  A cast was loaned for the public exhibition in Battersea Park for Elizabeth II's Silver Jubilee in 1977, and a cast was included in an exhibition organised by the Musée de l'Orangerie in Paris, and displayed in the Tuileries the same year.
The artist's copy, cast 0, is at Perry Green.Cast 2 is situated on the Seepromenade in the Seefeld district of Zürich. The sculpture has stood on the promenade since 1976, when it was sited as part of an exhibition of Moore's work.Another cast has been in the Kansas City Sculpture Park in Kansas City since 1976, in the grounds of the Nelson-Atkins Museum of Art. The purchase of the sculpture by the city was controversial, and it was bought using a legacy from N. Clyde Degginger intended for a monument to capture something of the unique "pioneer spirit" of Kansas.   It has been described as being pastoral, resembling bison but abstracted like boulders.The third commercial cast was exhibited the Clarks shoe factory in Street, Somerset from 1979 until it was sold to PepsiCo in 1991, for a price reported to be around £2.1 million.  It is now included in the Donald M. Kendall Sculpture Gardens in New York.
