Thought Signs

Book excerpt: The book is the first comprehensive encyclopedia of Western ideograms ever published, unique in its search systems, that allows the reader to locate a symbol by defining just four of its visual characteristics. It is about our graphic cultural heritage as expressed in subway graffiti, fighter jets' signs and emergency exit symbols. It contains 2,300 symbols, 1,600 articles and streamlined reference functions. Ideogram scarved in mammoth teeth by Cro-Magnon men 25,000 years ago, put on modern household appliances by their manufacturers or sprayed on walls by political activists, are all presented in dictionary form for easy reference. Symbols cover current designs used in advertising, logotyping, architecture, design, decoration, religion, politics and astrology.
