ABSTRACT:
Each card has one or more letters of the alphabet on its face, each letter comprising superimposed printed and cursive forms of substantially the same size with the coinciding portions thereof at a different level than the face of the card and/or than the remaining portions. Said remaining portions may be either of a different color from the coinciding portions and/or printed on the face of the card. The coinciding portions are tactually distinct from the remaining portions of the letters, i.e. connectors, smoothers and decorations, and these remaining portions may be tactually distinct from each other and/or the card itself, as by lowering them or raising them, using ridges, knoblike structures, roughness, different compositions or other means to distinguish them to the touch. Guide lines extend horizontally at the upper and lower extremities of the letter and at other significant parts of the letter either printed on the face of the card and/or at a different level therefrom.
