Given that these paintings had never hit the open market, their value remains difficult to ascertain. One estimate, made at the time of the theft by the museum’s then-managing director, put the pair at a combined $4 million, according to the New York Times.

One of the mysteries following the original heist surrounded the decision to take these particular paintings. Some burglars—like the notorious “Spider-Man” thief who was sentenced last month —consider themselves connoisseurs, stealing works that strike their fancy. But in a new documentary focusing on Durham that aired on Dutch TV the same day the van Gogh paintings went on view, the thief said he simply took the two works because they were the smallest in the room.

As the pair escaped by rappelling down a rope out of a museum window, a museum guard called the police. During the descent, Durham hit the ground with such force that he damaged a corner of View of the Sea at Scheveningen. Visitors to the Van Gogh Museum today can see the damage to the work (both are displayed sans-frame, as they were found, and will be restored following the conclusion of their exhibition on May 14th).

Durham monitored the responding officers on a police scanner, and was able to get away by taking off his ski mask before he drove by them.
