When museums are left with so little money that their future is in the hands of private donors, then they are unable to develop their own signatures by collecting themselves. On the other hand, though, I think we should also celebrate the fact that there is a lot of art that lives outside of, or on the outskirts of, the art market - and it is doing quite well.
