What makes someone spend many millions on one painting? Is it ostentation, a desire for publicity, investment potential, acquisitiveness, or a real love of the object?
Sadly the last is the least important, if it figures at all.
What pleasure can such a collector get from filling a bank vault with racks of purchases that they rarely see?
In truth they are not collectors at all, they are accumulators and we cannot stress enough that you should buy only what you really like.
