Brooks Mason asks in The Art Newspaper where collector/dealer/decorator Alex Vervoordt gets art:

TAN: Where do you source your material?

AV: Around 20% of the antiques and art come from the sales rooms; the rest we buy privately. Many times we buy back works from our clients and often go directly to artists such as the Zero Group. In acquiring contemporary art, you have to know that in five years time the work will be enormously important. I bought my first Fontana in 1969 and I love it. In 1998, I bought Anish Kapoor’s first major sculpture, At the Edge of the World. It’s eight metres in diameter. In those days, it cost a fortune, $2m. Now that seems cheap and I will never sell it.
