For Fall XII (1992) and Fall XIII (1992) Stezaker uses source material from an essential book by anatomist and anthropologist Arthur Thomson (1858-1935), A Handbook of Anatomy for Art Students (1896), a core text for students at the Slade School of Fine Art until the 1970s. The artist's collages at first, seamlessly combining two images, seem as if they are traditional nudes but in Fall XII, the front and the back of the figure are disconcertingly presented as one. And in Fall XIII, a male and female fugure are spliced together, the absence of faces and genitalia encouraging ambiguity.
