Art riches revealed in apartment that was abandoned for 70 years

Opening that door must have been an amazing experience. Even more incredible is that a Parisian flat - in the 9th no less, not the 7th or 8th - was not burgled over that period of time.

Entering the untouched, cobweb-filled flat in Paris' 9th arrondissement, one expert said it was like stumbling into the castle of Sleeping Beauty, where time had stood still since 1900.

"There was a smell of old dust," said Olivier Choppin-Janvry, who made the discovery. Walking under high wooden ceilings, past an old wood stove and stone sink in the kitchen, he spotted a stuffed ostrich and a Mickey Mouse toy dating from before the war, as well as an exquisite dressing table.

But he said his heart missed a beat when he caught sight of a stunning tableau of a woman in a pink muslin evening dress.

The painting was by Boldini and the subject a beautiful Frenchwoman who turned out to be the artist's former muse and whose granddaughter it was who had left the flat uninhabited for more than half a century.
