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.
Mona Lisa replicas and reinterpretations
Mimicking the heavy pixelation of a highly magnified computer file, Canadian artist Robert McKinnon assembled 315 Rubik's Cubes into a 36 by 48 inch "Mona Lisa" mosaic, an effect dubbed "Rubik's Cubism" by French artist Invader.
Similarly, colored Lego "bricks" have been employed to replicate "Mona Lisa" in a mosaic motif.
A 2011 exhibition titled "Da Vinci, The Genius" at the Frazier Museum in Louisville, Kentucky attracted attention by having a "Mona Lisa" constructed by Lego artist Brian Korte.
Known as "Brick Art", so-called "pro" Lego builders such as Eric Harshbarger have made multiple replicas of Mona Lisa.
Matching the approximate 21 by 30 inch size (535 x 760+ mm) of Leonardo's original requires upwards of 5,000 standard Lego "bricks", but replicas measuring 6 by 8 feet have been built, requiring more than 30,000 bricks.
