"Urban art - the decoration of public spaces - combines street art and grafiiti and is an international creative practice. many urban artists address issues such as human rights. the environment and lifestyle choices by challenging and confronting everyday thinking. Some artists feature heroes or icons in their work, others use illusion to lure the viewer into examining the art and trying to figure out what is real and what is not. Others still pay homage to less well-known people who have worked for the good of humanity. Along with the urban landscape, this art form is evolving all the time, reflecting the zeitgeist, asking questions, and grabbing the attention of the passing city dweller."--Back cover.
