Signs of Change is both a coffee table book and a full-color history lesson. For those who prefer an alternative to a boring textbook, this book is the ticket. In September of 2008, Exit Art began a traveling art exhibit to showcase the works of artists whose materials reflect cultural and social uprisings around the world, including posters, photographs, and graffiti. The pages are full-color and let the art take center stage, but historical context is provided in a way that is educational without being stifling.
