The October sale of the collection of Pierre-Yves le Diberder is estimated at €1.5m.
“Since the successful association of our auction housese in 2009 there had not been any other occasion to share knowledge and expertise,” said Raymond de Nicolay of Pierre Bergé.
Le Diberder spent more than ten years compiling his collection with the help of decorator Jean-Paul Faye.
Among the lots to appear at the auction are a Roman marble torso of Bacchus Ephebe, €15,000-20,000), a late Empire chandelier attributed to Thomire (€30,000-50,000) and a drawing by Fernando Botero (€30,000-40,000).
The Yves Saint Laurent sale held jointly between the two auction houses took a total of €373.9m (£332.8/$483.8), the highest total for any single-owner collection.
The le Diberder collection will go under the hammer at Drouot on October 13 and 14.
