Leonardo Da Vinci painted another Mona Lisa and, after 35 years of research, the artwork’s anonymous owners have the evidence to prove it.

The Mona Lisa Foundation announced today that it would reveal definitive proof that Da Vinci painted the “Isleworth Mona Lisa,” The Associated Press reported.

The group scheduled a press conference for Thursday in Geneva, Switzerland.

The Isleworth Mona Lisa is also of a woman with a mysterious smile, but the artist painted it on a larger canvas using more vivid colors.

It predates its more famous sister by 10 years, the AP said.

Da Vinci’s confirmed, 16th-century masterwork hanging in the Louvre – also known as La Giaconda – is painted on a panel.

Experts say the subject sitting for the Isleworth is a woman in her 20s, while they believe Mona Lisa is in her 30s, Reuters reported.

“We have investigated this painting from every relevant angle and the accumulated information all points to it being an earlier version of the Giaconda in the Louvre,” art historian Stanley Feldman told Reuters.

Art critic Hugh Blaker bought the second Mona Lisa in 1914 and brought it to his home in the Isleworth district of London.

Its authenticity as a Da Vinci work has since been challenged.

The foundation is also planning to release a book, “Mona Lisa, Leonardo’s Earlier Version” along with the new evidence.
