2010: Pablo Picasso's electrician, Pierre Le Guennec, reveals 271 previously unknown works by the artist (seen here in 1961), claiming they were gifts from Picasso and his second wife, Jacqueline. Le Guennec installed burglar alarm systems at Picasso's numerous houses in France during the three years before the artist died in 1973. The cache of work, which dates from 1900 to 1932 and includes lithographs, portraits, watercolors and sketches estimated to be worth $80 million, came to light after Le Guennec and his wife contacted the Picasso Administration to authenticate the works. Picasso's son Claude Picasso, convinced the works of art were stolen, contacted the authorities and the Le Guennecs would be indicted in May 2011. All the artwork has been seized pending a court verdict.
