The Daily Mailreports that a sketchbook containing 33 original Picasso drawings was stolen from the Picasso Museum in Paris. The sketchbook is said to be worth about $16.3 million.
It is the latest in a long serious of thefts of the legendary Spanish artist's work in the French capital, where he produced some of his finest work.
Police said the book was taken from the Picasso Museum in the Marais district of the city, close to the River Seine, on Monday night or early on Tuesday morning.
There was no sign of a break-in, suggesting that professional art criminals could well be behind the crime.
Alarms in the fortified museum were somehow switched off, and no windows were smashed or doors broken open.
There are said to be similarities between this theft and the theft of two Picasso paintings stolen from his granddaughter's home in Paris in 2007.
