Assessment
If you have a work of art that is signed with the name Constant and you would like confirmation of its authenticity you can submit the work for research by Fondation Constant. When we research a work for an authentication we do publish the results on our website. In case of an authentic work it will be part of the catalogue raisonné [WORK] and in case of an infringement of copyright, misattribution or forgery we will post it on the page Doubtful Origin.
NB: We do not afford economic valuations of work by Constant. In addition Fondation Constant does NOT give out certificates of authentication.
NB: TERMS AND CONDITIONS apply!
Oral assesment
After receiving the application form, photo’s and documentation, a telephone call or meeting for the oral assessment will be scheduled. An oral assessment is free of charge. NB: this assessment does not include extensive research nor any written statements and/or oral statements to third parties!
Written statement
After receiving the application Fondation Constant sends an invoice. When the payment is received, an appointment is scheduled to inspect the object first hand (if possible). In the meantime research is conducted on the documentation and the provenance. When the research is concluded and three experts have separately reached their conclusions a written statement will be issued. If the work is deemed an original by Constant a certificate of documentation is provided and the object will be added to the catalogue raisonné.
