Some one has ever seen this painting?

It is very difficult establish if a portrait of Georges Croegaert is genuine without see it by person; I have a genuine portrait by Croegaert, oil on canvas, but I Know tyat there are many copies sold as genuine.
You must show your painting to someone qualified as people that works in a museum where there are some paintings of the same artist. Would you show a foto of this painting?
