After 10 long years of study, Pascal Cotte, a french scientist, claimed that there is indeed a portrait of another woman underneath "Mona Lisa" painting. And according to Cotte, it is not the same woman. It does not have the famous Mona Lisa smile.
However, other scientist does not agree with Cotte. It still a long process and study to go before it can authenticate and approved.
If this is true, many people would wonder, who is the woman beneath the "Mona Lisa' painting?
