10 artworks that changed the world

Artworks can be shocking, outrageous, breath-taking and rule-breaking. But some go even further and manage to leave a legacy so powerful, it can be called world-changing. This book looks at 10 of these artworks - from the prehistoric cave paintings in Lascaux that revealed to us how innate art really is to being human, to Banksy's Sweeping it Under the Carpet, which used art as a political statement, painted on a gallery wall.
