Authentication Services

We are often asked to authenticate works that may have been painted by Julien Dupré. To have your work authenticated, please send us professional high-resolution digital files (at least 8 x 10 inches, 300 dpi) of the front, back, and signature area of the piece. We also need a completed Input Sheet (see below).  In return, we will provide you with a photo-certificate.  In certain instances it may be necessary for the work be sent to us for our inspection. If you prefer, you can print and mail the PDF form along with a check.

The fee for this service is $1,500.00 and only one photo certificate will be issued for a work.  This certificate is an important document concerning the works authenticity and should the work be sold, or given to someone, the certificate should accompany the work. By using this service, you will also be granting us the right to reproduce the work in our forthcoming catalogue raisonné on that artist.
