You are looking at a book. On its cover is a painting of a person of colour. But you can only see a portion of the piece. The face is obscured. One dark eye takes up the middle third of the page, while one nostril fills the bottom right-hand corner. The painting is covered in a layer of fine cracks – presumably due to its age. These lines show that myriad individual pieces make up the image before you, but this is still only one part of the picture. Frustratingly, you cannot see the face as a whole.
