....and this definitely has the makings of one. McLaren, the owner of a painting that "might" be a daVinci work says the word "Magdalene" is clearly written on a paper attached to the back of this painting.
Fiona McLaren, 59, had kept an old painting in her Scottish farmhouse for decades. She reportedly didn't think much of the painting, which had been given to her as a gift by her father. But after she finally decided to have the painting appraised, some experts are speculating that it may in fact be a 500-year-old painting by Leonardo da Vinci and potentially worth more than $150 million.
The Daily Mail says the painting may be of Mary Magdalene holding a young child. The painting is now undergoing further analysis by experts at the Cambridge University and the Hamilton Kerr Institute, who will attempt to uncover its exact age and origins.
A papal bull was found attached to the back of the painting and is believed to have originated from the era of Pope Paul V, head of the Catholic Church in the early 17th century. McLaren says the word "Magdalene," is visible on the faded paper.
