We see symbols and signs every day; on commercial products, in advertisements, in art, on the Internet, and on buildings. Many signs and symbols were produced out of the simple need for people, who may not have been able to read, to understand them. Symbols have grown into icons representing love, hate, happiness, nationality, and religion. This volume explores some of these signs and symbols, how they came to be, what they mean, and what they could mean in the future.
