| Title | Presentation board titled 'Doorway Drawing'  | 
| Date | 1981 | 
| Description | Presentation board featuring a black and white photograph of an anamorphic drawing mounted on grey card. The drawing - of a copulating couple - has been painted in sections on the door and walls of an unidentified room. A typescript label gives the title, date and medium of the work.  | 
| Notes | An anamorphic image only reveals itself when viewed from a particular perspective or when viewed through a transforming optical device, such as a mirror.  'Doorway Drawing' can only be viewed at a certain point where sections of the drawing - painted on two walls, on the outside of a half-open door and reflected in a mirror - come together to form an image of a copulating couple.  |
