Isleworth Mona Lisa
According to Leonardo's early biographer Giorgio Vasari, Leonardo had started to paint "Mona Lisa" in 1503, but "left it unfinished". However, a fully finished painting of a "certain Florentine lady" surfaced again in 1517, shortly before Leonardo's death and in his private possession. The latter painting almost certainly is the one that now hangs in the Louvre. Based on this contradiction, supporters of the authenticity of the "Isleworth Mona Lisa" claim it is the unfinished "Mona Lisa", made at least partially by Leonardo, and the Louvre "Mona Lisa" a later version of it, made by Leonardo for his own use.
Lárus List
List, who is represented by British Lawyer Graham Ross, claims that the domain was registered in relation to a painting entitled "Wa1m-ART" which was displayed in Kling og Bang Gallery in Reykjavík. The painting is based on Leonardo da Vinci's Mona Lisa. List said the idea behind his Mona Lisa-based artwork was to criticize American greed and cultural hegemony and that Wal-Mart’s lawsuit has proven his point.
