This is a compelling study of the nature of signs and how people communicate, written by the distinguished typographer Adrian Frutiger, who has illustrated his text with over 2,000 line drawings. He reproduces numerous aspects of graphic symbolism from the simplicity of the T-sign to the ornamentation of the Australian aboriginal painting, and comments on the full range of symbols even including modern trademarks and traffic signs. This is the distillation of Frutiger's life's work and compulsory reading for all those interested in graphics, design, art, ornament and communication in general.
