The Assn. of Art Museum Directors sanctioned the Delaware Art Museum on Wednesday for selling its 1868 William Holman Hunt painting “Isabella and the Pot of Basil” this week to help make debt payments and build its endowment.

The painting, part of the museum’s permanent collection, sold for $4.25 million at Christie's, an incident that left the museum directors association “deeply troubled and saddened.”

“Art museums collect works of art for the benefit of present and future generations,” read the statement from the AAMD, which has long said artworks should be deaccessioned only to generate funds to acquire other works of art and to enhance a collection. “Responsible stewardship of a museum’s collection and the conservation, exhibition, and study of these works are the heart of a museum’s commitment to its community and to the public.”
