The Museum of Fine Arts, Boston is selling.
Remember, having fallen under the aegis of a museum, those objects are held in the public trust, to be accessible to present and future generations.
And potential future donors will certainly being asking, Why should I give this to you? What guarantee do I have that you're not going to sell it, just like you sold off those 30+ Tiffany objects?
That's the coin of the realm folks. Use your common sense.
