After reading the chapter on Scale and Proportion, the Typewriter Eraser exemplifies the use of scale and proportion.  It is a large scale sculpture of a typewriter eraser using the power of unusual scale to capture our attention. In relation to human size, we know a typewriter eraser should fit in the palm  of our hands yet the artist has chosen to represent the eraser in a 20' sculpture.  As indicated in the text, the size of the image actually changes our view of the common elements of a typewriter eraser from the flowing strands of the brush to the geometric shape of the red eraser portion.  Creating it at such a large scale changes our view of what was a very common item.  

A good example the power of unusual scale,  scale confusion, and contrast of scale by deliberate changing the sizer. Dramatic contrast was achieved with the kids playing around the image in the photograph as well as it's placement in front of the trees in the background.

The piece itself with the flowing brush strands and it's geometric shapes provides a certain degree of unity in the photograph.  The vibrant red eraser changes our perception of the photo and causes us to focus on the sculpture.  We eventually move our focus to the children playing which provides the contrast of scale, comparing the kids to the sculpture.
