A craft or work of fine art initially received on consignment shall remain trust property under section 4,¹ notwithstanding the subsequent purchase of the craft or work of fine art by the consignee, directly or indirectly, for the consignee's own account, until the terms of the purchase are completed. If the craft or work is resold to a third party who is a bona fide purchaser before the consignor has been paid in full, the work of fine art shall cease to be trust property, and the proceeds of the resale shall be trust funds under section 4 to the extent necessary to pay the balance due the consignor.
