Yves Chaudron was a French master art forger who is alleged to have copied images of Leonardo da Vinci's Mona Lisa as part of Eduardo de Valfierno's famous 1911 Mona Lisa painting theft. 
Doing DaVinci was a popular science television program originally aired on the Discovery Channel in which the hosts attempted to create many of Leonardo da Vinci's inventions.
The show aired on a weekly schedule with the first episode broadcast on April 13, 2009. 
It was viewed in 1854 and described as "a very fine work", but very dark.
In 1807 it was sold as a Leonardo da Vinci and fetched 280 guineas.
William Beckford sold it and Alexander Baring (Baron Ashburton) bought it from an intermediary shortly afterwards.
In 1968 the painting was bought at auction in London for less than $2,000.
A 2007 special titled "Da Vinci's Lost Code" on the Discovery Channel, featuring an interview with Dutch art dealer who bought it, stated the figure was $1500.
By late 1979 it had been viewed by a number of experts and a comparison made with the "Virgin of the Rocks" in the National Gallery, London, painted by Leonardo to fulfill a commission to the Confraternity of the Immaculate Conception, and probably also worked on by other hands, in particular the de Predis brothers with whom the commission was shared.
Another version of the work exists in the Royal Collection and is ascribed to Leonardo's pupil Marco d'Oggiono.
According to Stephen Holmes, who has written a book "The Lost Leonardo" (publication, 2007), the consensus among the experts was that it was from the same hand as the "Virgin of the Rocks" in London, and equal in quality.
Holmes points out the fine handling of the details, in particular the expertly painted anemones in the foreground of the painting which strongly resemble those in the "Virgin of the Rocks".
The painting has been the subject of an English language TV documentary ("Da Vinci's Lost Code" - Discovery Channel 14 May 2006) which examined the possibility that a number of versions of "The Holy Infants" painting were produced by various artists.
Moreover, it hypothesized that, whilst some were interpretations painted by various artists over the years, some may actually have been from the "da Vinci house" (i.e., painted by da Vinci's pupils), which may or may not have been contributed to by Leonardo himself. 
In 1972 Edelson used an image of Leonardo da Vinci’s mural to create "Some Living Women Artists / Last Supper."
She used collage to add notable women artist's heads of the men in Da Vinci's painting, which quickly became "one of the most iconic images of the Feminist Art movement."
John the Baptist's head was covered by Nancy Graves and Christ by Georgia O'Keeffe.
It confronted the role that society and religion has had in women's "subordination."
"Proposals for: Memorials to the 9,000,000 Women Burned as Witches in the Christian Era," a 1977 performance piece, had the same objective.
New York's Museum of Modern Art has the original work made by Edelson.
