The Zurich-based Mona Lisa Foundation has said it would present what it believes to be an earlier version of Leonardo da Vinci's Mona Lisa. The portrait will be shown to the media in Geneva on Thursday. The experts said they would present “the stunning portrait of Lisa del Giocondo,” along with results from 35 years of research and scientific tests indicating that “it was indeed executed by Leonardo approximately a decade earlier than its famous sister in the Louvre.” Some experts are skeptical about the issue saying that it is by far not the first attempt to prove that there had been an earlier Mona Lisa work.
