The winner of a Pablo Picasso painting worth €1m (£870,000; $1.2m) thought he was being scammed when he heard the good news, a charity raffle organiser has told the BBC.
Péri Cochin told Radio 4's Front Row that she had to show Ari Hodara the artwork he had won on a video call from Christie's auction house in Paris before he believed she was telling the truth.
The raffle sold more than 120,000 tickets at €100 each to entrants around the world, raising €11m (£10m; $13m) for Alzheimer's research.
She says Hodara is still deciding whether he will keep or sell his grand prize.
