In accordance with the revised statute of 16 May 1990, decree no. 90-404, governing Curators, the curators of the Musée d'Orsay are not authorised to authenticate or value works of art. You should therefore contact a professional expert. These can be found in a list on the website of the union of professional experts on works of art and collectable objects: http://www.franceantiq.fr/sfep/uk.asp.
The public establishment of the Musée d'Orsay does not provide certificates of authenticity for works of art. Any certificate of authenticity purporting to be from the Musée d'Orsay is therefore false, and its use is an offence under articles 441-1, and following articles, of the French penal code.
