Authorities are offering a reward of up to $25,000 for information leading to the recovery of Andy Warhol paintings stolen from a Missouri museum last week.

The break-in occurred at the Springfield Art Museum early Thursday, according to the FBI.

Seven of 10 Warhol paintings on permanent display were taken.

The collection is set number 31 of the "Campbell's Soup I" collection, the FBI said. It's valued at some $500,000.

Each painting in the screen print collection is 37 inches high by 24.5 inches wide.

The collection has been owned by the museum since 1985.
