I carried on buying paintings, works of art, and Yves Saint Laurent, if I may say so, had a right of inspection. We even shared a common reading of the history of art. It would never have crossed Yves's mind to say to me, "Ah, I saw a Pablo Picasso . . ." He knew perfectly well what was interesting with Picasso, as did I.

On my own account I certainly wouldn't have become the director of a couture house. I didn't have sufficient admiration for fashion as such to have done so.

In April 2007 I learned that Yves Saint Laurent had a brain tumor, and he died on June 1, 2008. During those 14 months I had plenty of time to think about what would happen. There was only one solution: the auction. An auction establishes memory. That's what I want to do.

The problem with Yves Saint Laurent was that he was a man who understood his time period better than anyone, but he didn't like it. Real artists live their own lives in parallel. It's the artist who transforms his times.

I am a man who has spent more than half a century ostensibly and visibly accompanying Yves Saint Laurent throughout his life - but not only that. In the past and still today, I have been behind a lot of creators and artists, supporting them and helping them. That's probably how I see my mission.

I am faithful up to the point of death. It's the only thing I respect. I never abandon anyone. I'm not talking about sexual relations. I'm faithful in my friendship, my admiration.
