Grand Theft Picasso

Sometime between sundown on Monday evening and the break of day on Tuesday, the Musée Picasso in the Marais was robbed of a prized item: a red notebook containing 33 sketches by the master himself.

The notebook, which was housed in a secure glass exhibition case on the second floor of the museum, is estimated to be worth 8 million euros (approximately $11 million).

The theft was only discovered when a museum employee (not museum security) noticed the book missing from the display case on Tuesday morning. According to the French Ministry of Culture, there were no surveillance cameras in the room containing the sketchbook. The museum is closed to the public on Tuesdays.

This is not the first time works by Pablo Picasso have been stolen—in 2007, two of his paintings and a drawing were stolen from a house belonging to the artist’s granddaughter, although they were later recovered. In 1994, seven Picassos were stolen from a Zurich gallery, and were only discovered in 2000.
