“The first sentence of the AAMD handbook guiding deaccessioning policy … says: ‘The board of an art museum should adopt a written policy pertaining to the deaccessioning and disposal of works of art from its collection.’ That doesn’t sound to me like the profession (or its ‘supporters’) thinks works in museum collections cannot be sold. It sounds like they think that, when such sales inevitably happen, they need to be done with forethought and care.”
