Hello and welcome! My name is Doris.I have been an antiques collector, dealer and appraiser for over 56 years.I will be pleased to help you.
Please know that I cannot accept any requests for "live conversations" such as phone calls. I must research up-to-date data to give the most accurate answer.
Sometimes my customers click the wrong button when they really do not want a "live conversation." Please be careful what choices you click on.
I might be able to compare signatures but no one can authenticate a painting from a few photos. Accurate authentication can only be done in person.
If my trying to match the artist's signature is enough for you, please let me know.
If you would like, you can send me a photo of the signature. I would be happy to look for the match.
You may need to use the macro function (flower icon) of your camera to get a good clear photo of the signature.
To send photos you may use the "attach" or "add" link or "paper clip" you see on your reply page.
In addition, I can tell you if the style of your painting matches that of Michel Henry.
Let me know if that works for you.
Or I could suggest an appraiser in your area.
