A small oil painting by French Impressionist Pierre-Auguste Renoir has been stolen from a sale room near Paris, the day before it was due to go up for auction.
The piece was on display ahead of the auction in Saint-Germain-en-Laye when it was removed on Saturday.
It had an estimated sale price of between €25,000 and €30,000 (£22,000 and £26,500; $29,500 and $35,500).
Police hope surveillance footage will provide clues about the theft.
Measuring just 14cm by 12.2cm (5.5ins by 4.5ins), the Portrait d'une Jeune Fille Blonde (Portrait of a Blonde Young Girl) includes the initials AR in the top left corner.
