DUFY Art Authentication: Before you begin
Before entering into a full investigation of the legitimacy of a work of art which you believe may possibly be by Raoul Dufy, be it academic, forensic; or as with most cases, both, it is essential to know if the project is viable and more importantly, a provable issue.
Much the same as you would need to know if you were taking a legal case to court. Because at this level, society demands high respect. So there is no place for unsupported hypothesis, assumption, supposition and opinion alone.
In order to judge the issue of viability, we always prefer to make a preliminary and vital professional pre authentication assessment for clients first. One based upon the images you supply and the full details of the work of arts history and provenance as known.
Logically, if it is not realistic to do so, you should not attempt it, as the risk of failure is too high.
This is a cost effective professional assessment and advisory service for which there is a modest set fee.
