$10M Isabella Stewart Gardner Heist Reward Extended

BOSTON, MA — If you were on the fence about letting officials in on the largest art heist in U.S. history, you've still got time to make eight figures on it. The Isabella Stewart Gardner Museum announced Thursday it was extending the $10 million reward its offering for information leading to the recovery of the 13 pieces of art stolen in 1990.

The reward for the art, stolen in 1990, now sits at $10 million and is good through the end of 2018. The reward was $1 million until 1997, when it was increased to $5 million, which was the largest private reward in the world.

More than $500 million of art was taken.

"These works of art were purchased by Isabella Stewart Gardner for the education and enjoyment of the public forever," said Steve Kidder, president of the board, in May. "It is our fervent hope that by increasing the reward, our resolve is clear that we want the safe return of the works to their rightful place and back in public view."

The art was stolen in the early hours of March 18, 1990. A pair of thieves disguised as Boston Police officers allegedly gathered the two security guards on duty and used handcuffs and duct tape to secure them in the basement.

The thieves left with work including Veermer's The Concert, Rembrandt's Christ in the Storm on the Sea of Galilee and A Lady and Gentleman in Black, Manet's Chez Tortoni, and Edgar Degas' Leaving the Paddock. Some items are considered among the most valuable stolen items in the world.
