That picture has not been altered. It is, in fact, a detailed painting of Yoda barely bigger than a nail. Painted by Karen Libecap, its one of many pieces of tiny art that this Alabama woman has made over the years. People who know Karen might not be as suprised, given her twenty five years of art experience and her time as Art Director in Chicago and Columbus, Ohio.
Still, where else are you going to see such a tiny piano? Karen works on commission on her Etsy page.
