L' Art Francais Prints

Hi,

Not sure if this is going to be helpful or not, but the gallery information and history about it is here: http://www.galerievalentin.com/about-valentin-gallery.html Louis Lange passed away and his wife ran the gallery which was later purchased by Jean-Pierre Valentin. You may have some luck contacting them at: [email protected] or phoning them at (514) 939-0500 and perhaps with a photo of your work they may be able to tell you about the artist and possible valuation. Hope this helps.
