We've all felt strongly about a work of art. Whether it was wishing Guernica had a bit of color or that Mona Lisa cracked more of a smile, some of us go to greater lengths than others to deal with our opinions. Some go so far as to vandalize a work of art, but that's getting a bit carried away. This book allows you to happily "improve" a variety of 12 artworks from the comfort and safety of your armchair, including The Birth of Venus, The Last Supper, The Creation of David, Night Watch, Girl with a Pearl Earring, and more. Using the supplied pens you'll be making your point in less time than it takes an art critic to denounce Banksy. Then you can wipe it clean and start again.
