The reward was set to run until the end of December but the museum has chosen to keep it open following a number of people making contact shortly before it was set to expire.
The works taken in the robbery on March 18, 1990 included Vermeer’s The Concert, Rembrandt’s Christ in the Storm on the Sea of Galilee and A Lady and Gentleman in Black, Édouard Manet’s Chez Tortoni, and Edgar Degas’ Leaving the Paddock. It remains the largest art heist in history with the combined value of the works estimated at $500m.
The original reward offered was $1m but that was raised to $5m in 1997. The reward was then doubled to $10m in May 2017.
