the beyeler family exchanged their art collection into a foundation and a museum. visitors exchange money for an entry into that museum of modern art. that is the economic transactional view.
the real exchange is more interesting. there are subtle elements involved. the entry provides the opportunity to see the art in a beautiful building. the people come to appreciate the art in this particular setting and museum appreciates its art loving visitors (that was the whole point of establishing the foundation). these appreciations circle around curiosity, awe and being part of a kind of elite of the beaux arts. status, self reflection, insight, money, the heritage of ernst and hildy beyeler, the meaning of art and the individual works of art, the livelihood of the artists, all are ingredients of the true and more complex exchange. It os this particular exchange that contribute to the succes of this purposeful social space.
many museums share this kind of exchange of values.
