I'm confused why you would make such a statement Ian. Do you have reason to believe that the museum is mistaken about what it has in its own collection.
I live about 40 minutes south of the Dayton Institute of Art. Its a fine and respected institution with a sizable collection that regularly also hosts world class traveling exhibitions.
