The four full-size casts are at the Henry Moore Foundation in Perry Green, Hertfordshire, in Zürich, in Kansas City, and at the Donald M. Kendall Sculpture Gardens in Purchase, New York.

In the book Makers of Modern Culture, Patrick Conner describes the "power" of Sheep Piece as not only lying in the "physical confirmation of two massive structures but also in the psychological overtones of warmth and protectiveness that their relationship suggests".

[8] 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.

[13] 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.

[15] 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.
