A most evocative book… [It] is no guide to the learning of the sign language itself, but it is one to understanding it as an independent flowering of the capacity we call language. That is a treasure richer than speech, sign or ideograph, the springs of both art and science. It is worth mention that for the many sequential drawings and diagrams needed to make the flow of sign understandable on the static page the authors have themselves evolved a small visual language of symbol: an entire set of spiraling, swelling and dwindling arrows bridging their scenes. The two hemispheres of the brain are plainly cooperating in this study!
-- Philip Morrison Scientific American
An excellent book… It can be recommended not only to the specialist, but to readers with no previous knowledge of sign language.
-- Peyton Todd Journal of Communication
A major contribution to our understanding of signs; of particular interest is the chapter dealing with puns or plays on signs… The illustrations are outstanding.
