The Zurich-based
Mona Lisa Foundation
Known as the "Isleworth Mona Lisa," the painting is a "portrait of a young woman with an enigmatic smile" much like the famous work of art in The Louvre,

Among the foundation's evidence:
-- "
Historical accounts
-- "
Scientific and physical examinations
The foundation's claims aren't impressing some skeptics. According to the AP:
"Martin Kemp, an Oxford University professor and Leonardo expert, wrote in an e-mail that 'the reliable primary evidence provides no basis for thinking that there was an earlier portrait of Lisa del Giocondo' — referring to the subject of the painting that's known as the Mona Lisa in English and La Joconde in French."Kemp questioned the 'debatable interpretations' of source material about the Isleworth painting, and said that scientific analysis cannot categorically deny that Da Vinci didn't paint it. However, he added: 'The infrared reflectography and X-ray points very strongly to its not being by Leonardo.' "
