Return requirement: packaging and certificate of authenticity
Packaging: The return will be systematically refused or penalized if the artwork is not returned in its original secure packaging (envelope, tissue paper, triple-corrugated cardboard, specific bubble wrap, etc.) or a similar art package if the original one is damaged.
Certificate of Authenticity: The original Certificate of Authenticity must be included. Without this document, the artwork loses its market value and the return cannot be validated.
