Times are tough for art institutions and foundations across North America. And one of the dirty little secrets of the business is that such organizations frequently keep themselves afloat fiscally by selling off bits of their collections. But is it ethical to do so?

But for foundations which refuse to give up any piece of their collections, (such as Philadelphia’s notoriously strapped Barnes Foundation,) the alternative can be serious financial hardship and even insolvency.
