Exquisitely detailed, realistically portrayed hands of different ages, sexes, and colors demonstrate the positions for the manual alphabet used in American Sign; an object with the appropriate initial appears with each--the pointing finger for ""T"" reaches toward a dripping icicle; ""T"" sports three thimbles and a fistful of thread; ""X"" appears on an X-ray. An elegant roman capital completes each beautifully designed color-pencil illustration. The key includes the lovely jacket and title-page pictures, each of which adds something special--e.g., the hand on the title-page is overlaid with some of the many styles of letters that may be represented by the signs. The point of view sometimes varies from signer to observer, but the illustrations are so admirably clear that this should cause no confusion. An excellent introduction.
