The Springfield News-Leader reports the FBI announced the reward Monday.
The FBI says the break-in at the Springfield Art Museum took place early on April 7 and involved the theft of seven of 10 Andy Warhol prints on permanent display. The site's Warhol collection is valued at $500,000.
City spokeswoman Cora Scott says the museum is a city department funded through property taxes. She says all the works at the museum are covered by a fine arts insurance policy that has an annual premium of roughly $14,000.
