Oops, sorry, Claude Monet, below !!
Five masked gunmen broke into the home in Le Pecq west of Paris in the early hours on Monday, sequestered the art dealer and fled with the artworks, said police.
A judicial source said that if the authenticity of the artworks is confirmed, the heist would be "priceless."
The thieves' burnt and abandoned 4x4 vehicle was found in a nearby wooded area on Monday.
The antiques dealer was robbed once before, in 2004, but the paintings stolen then were recovered.
