Deibel has composed a fine collection of line drawings of his artifact interpretations. These line drawings will be of great assistance to anyone new to the portable rock art subject. If you are looking at artifacts here and thinking "I don't see it," the drawings will illustrate how the visages are interpreted by Allen and others. The images are often comprised of combinations of color and relief in the stone material and are sometimes difficult to capture and communicate in photos.
He has also perfected the technique of figure stone presentation using chopsticks, a fine example of this innovation seen above. Work of James Thurber below.
