The FBI is offering $25,000 to anyone who can help the Springfield Art Museum in Missouri recover seven identical Andy Warhol paintings that were stolen last week.

The federal agency was called in April 7 to investigate the disappearance of $500,000 worth of pop art masterpieces, all of which feature the same picture of a Campbell's soup can.

Investigators believe one or more people broke in to the museum in the early morning hours and stole seven of the 10 Warhol paintings, which have been on display at the museum for more than 30 years.

The paintings are 37 inches high by 24.5 inches wide and are encased in white frames.
