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".

The "Isleworth Mona Lisa" is wider than the "Mona Lisa" in the Louvre, having columns on either side which also appear in some other versions.
The Louvre painting merely has the projecting bases of columns on either side, suggesting that the picture was originally framed by columns but was trimmed.
However, experts who examined the "Mona Lisa" in 2004–2005 stated that the original painting had not been trimmed.
The figure of the "Isleworth Mona Lisa" closely resembles that of the "Mona Lisa", being identically composed and lit.

Several people Pulitzer consulted believed that the hands and face of the portrait were by Leonardo, but the rest may have been finished by another or others.
The background in the Isleworth painting is considerably less detailed than the background in the Louvre painting, causing many art experts cited in Pulitzer's book to suggest that if Leonardo did indeed paint the subject, it is likely somebody else painted the background.

 and the Isleworth Mona Lisa.
Shortly before World War I, Hugh Blaker discovered a painting of the Mona Lisa in the home of a Somerset nobleman in whose family it had been for nearly 100 years.
This discovery led to the conjecture that Leonardo painted two portraits of Lisa del Giocondo: the famous one in The Louvre, and the one discovered by Blaker, who bought the painting and took it to his studio in Isleworth, London, from which it takes its name.
According to Encyclopedia Americana and The New York Times, The Isleworth Mona Lisa has been attributed to Leonardo, and is thought to be the unfinished portrait from which Raphael made his famous sketch (which is in the Louvre museum), and is in no sense a copy of the Louvre Mona Lisa. 
Lisa del Giocondo (; née Gherardini ; 15 June 1479 – 15 July 1542 or ca.
1551), also known as Lisa Gherardini, Lisa di Antonio Maria (or Antonmaria) Gherardini and Mona Lisa, was a member of the Gherardini family of Florence and Tuscany in Italy.
Her name was given to "Mona Lisa", her portrait commissioned by her husband and painted by Leonardo da Vinci during the Italian Renaissance.
Little is known about Lisa's life.
Born in Florence and married in her teens to a cloth and silk merchant who later became a local official, she was mother to five children and led what is thought to have been a comfortable and ordinary middle-class life.
Lisa outlived her husband, who was considerably her senior.
Centuries after Lisa's death, "Mona Lisa" became the world's most famous painting and took on a life separate from Lisa, the woman.
Speculation by scholars and hobbyists made the work of art a globally recognized icon and an object of commercialization.
In 2005, Lisa was definitively identified as the model for the "Mona Lisa".
