Sacrifice (1992) was Michael Riley's first major series of conceptual photographs. The release of the Sacrifice box set coincided with the retrospective, Michael Riley: sights unseen, at the National Gallery of Australia, in 2006, which toured nationally.

The Sacrifice box set is an edition of 20 + 1AP (+ exhibition set). It differs in size, print type and hue to the larger edition and is only available as a full series of 15 images.

The Sacrifice box set is in the collection of the Art Gallery of Western Australia and the Sir Elton John Collection.
