model with mirror

Sep 2013
A book is on a horizontal table. Is it possible to read the book easily in a mirror which is placed exactly perpendicular to the table. What is the required minimum number of mirror to make the model and how to make it?

Schematic diagram of the problem is attached. The problem can be thought as to see the keyboard of a computer in its monitor without any change in its shape.

I would have thought that the arrangement you want ought to be possible with two mirrors.

Mirror one would be placed above the desk angled away from the viewer
such that it reflects the image of the book toward the second mirror:
