The Mona Lisa is considered the most famous and recognizable painting in the world today. The painting is said to be a portrait of Lisa Gherardini who is the wife of Francesco del Giocondo. The Mona Lisa gained much of its fame due to it being stolen in the early 20th century. In 1962 the painting was assessed for insurance at $100 million and adjusted for inflation it would be worth around $760 million today making it the by far the world's most expensive painting.
