A second group of artworks from the collection of the late fashion designer Yves Saint Laurent and his partner Pierre Berge is expected to fetch up to 4 million euros ($5.7 million) when it appears for sale in November.

Christie’s International’s YSL Part II sale, held in collaboration with Pierre Berge, will take place at its Paris auction rooms on November 17, 18 and 19.

Almost 1,200 pieces will be offered, about half of them from the couple’s coastal retreat, Chateau Gabriel, at Benerville near Deauville in Normandy.

Saint Laurent and Berge bought the 19th-century seaside mansion in the early 1980s.

It was decorated by interior designer Jacques Grange in an opulent, fin-de-siecle style inspired by Marcel Proust’s novel “A la Recherche du Temps Perdu.”

All of the more valuable works from the collection were sold in Christie’s record-breaking Saint Laurent sale at the Grand Palais in Paris in February.

The total of 342.5 million euros was the highest ever achieved at auction for a private art collection.

Proceeds of the sale will benefit HIV research and the fight against Aids, said Christie’s. Bloomberg
