A leading Greek art expert has described two suspects who received a stolen 17th century artwork and were then arrested when they left the museum label on the back as "amateurs."

The painting - one of several versions of "The Calydonian Boar Hunt" by Flemish master Peter Paul Rubens - was stolen in Belgium a decade ago and recovered in Athens in a Sept. 1 police raid.

Police and Greek cultural authorities presented the painting Thursday. A 64-year-old man and 40-year-old woman accused of receiving the stolen work have been charged with money laundering.

National Art Gallery director Marina Lambraki-Plaka referred to the two Friday as "amateurs - unless they had some other reason for keeping the identification details on the back of the painting."
