I just bought Luke's book.

It has 21 page, printed on stiff card (might be waterproof, I haven't tested it), with 22 roughly half page black and white photos. Image quality is grainy, but is well labelled so that you can tell which side is the blade edge. The idea is that it is a book that you can take into the bathroom with you, and consult as you start to shave.

Sections are:

Opening the Cutthroat
Closing the Cutthroat
Holding the Cutthroat
Angling the Cutthroat
Shaving the Moustache Area
Shaving the Neck Area
Shaving the Cheek Area
Shaving the Jaw Line
Shaving the Chin Area

Luke only describes shaving in the direction of growth.
