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
""Mona Lisa" (Two Times)," "Four "Mona Lisa"s," and "Thirty Are Better Than One" illustrate Warhol's method of silkscreening an image repetitively within the same work of art.
Also in 1963, Fernando Botero – who had already painted ""Mona Lisa", Age Twelve" in 1959 – painted another, this time in what would become his trademark "Boterismo" style of rendering figures disproportionately "plump".
"Mona Lisa" is also referenced in artwork by Contemporary art luminaries such as Jasper Johns and Robert Rauschenberg, adding to the veritable "who's who" list of artists putting their own spin on the portrait.
A paint by numbers version of "Mona Lisa" accompanied artist Suzanne Lacy during her 1977 travelogue "Travels with Mona", documenting the painting process at landmark locations throughout Europe and Central America.
From the 1980s through the end of the 20th Century, "Mona Lisa" continued to be the subject of re-interpretation among a new generation of emerging artists.
Street artists such as Jean-Michel Basquiat and Keith Haring, who came into prominence in the 1980s, created "Federal Reserve Note" and "Apocalipse 7", respectively, juxtaposing "Mona Lisa" within compositions suiting their styles.
Ballpoint art pioneer Lennie Mace created his "Mona a'la Mace" replica in 1993, a ballpoint "PENting" commissioned by Pilot pen company and featured on CBS News.
Artist Sophie Matisse, great-granddaughter of artist Henri Matisse, in her 1997 "Monna Lisa (Be Back in Five Minutes)" faithfully replicated the setting of the original painting, but omitted Mona Lisa from the scene; a concept she would repeat using other iconic artworks.
