Laurence Sallenave, the artist’s great-niece, is the only person authorised to issue certificates and authenticate a work. She was close to her great-uncle throughout her childhood and is the sole holder of his moral rights. She will issue a certificate only after inspecting the work. Every request for authentication is systematically archived.
