Thieves Swipe Andy Warhol Soup Cans Collection From Missouri Museum

A collection of pop artist Andy Warhol's iconic "Campbell's Soup Cans" prints has been stolen from a Missouri art museum. The FBI on Monday posted a $25,000 reward for information leading to the artwork's recovery.

The seven stolen prints, which the FBI valued at $500,000, are part of a collection of 10 owned by the Springfield Art Museum, in Springfield, Missouri, since 1985, according to KCTV News.

The museum said in a statement the burglary occurred sometime after hours on April 6 or early April 7. Its exhibition where the Warhols were on display -- entitled "The Electric Garden of Our Minds: British/American Pop" -- is closed as a "safety measure," the museum said.

The FBI reportedly said Monday that the stolen works are part of set number 31 of Warhol's 1968 "Campbell’s Soup I" collection.

Sally Scheid, chair of the museum's board, told the Springfield News Leader she was "shocked and totally saddened" by the burglary, which she called "an invasion of the trust" the museum has with the community.

Warhol's works have been known to fetch incredible prices. In 2008, for example, a 12-foot-tall painting called "Eight Elvises" sold for more than $100 million.
