On tonight’s “Blank Canvas,” NAGB Director Amanda Coulson meets with Mark Aronson, Chief Conservator at the Yale Centre for British Art, a position he has held since July 2007. Art conservation is something The Bahamas sorely needs, yet we have no professionally accredited conservators in the nation to care for any of our paintings, sculpture or other art works. Mr. Aronson is in The Bahamas to view the National Collection and to train local staff on how best to care for the works on a day-to-day basis.
