I am thinking to buy an item of impressionist painting with a certificate which says this is to certify that this is a pencil signed silkscreen of Le Blanc, document dated in 1985. He is probably not the Julius Leblanc stewart. I don't know if it is worth of buying it. Debating between this one and an original lithograph by Chagall from the same person with certificate also from 85, that original sign in stone after / by Chagall.


Hello Kian;
Thank you for this very interesting and unusual question.
This is a very tricky question to answer.
Often, when discussing such delicate matters, a  more concrete visual object  is represented and clearly shown.
In this case however, most of the “bones of the matter” are not visible.
Given the fact, that no visual representations and other documentation are available , then my best advice would be;
Caveat Emptor – Buyer Beware.
Be sure of the source, from which you are buying - and get a full provenance research.
Get HQ  imagery of the artefacts in question, then and seek professional advice from  at least - 2 reputable auction  houses for  further advice.
Certificates are pretty much worthless, however - proper lab forensics are far better, but are also more costly.
The market is awash with fakes and if it appears - too good to be true, then it may well indeed be  so!  
Therefore starting points would be Sothebys and Christie, but also Bonhams.
The yellow pages will all point you in the right direction.
I wish you, very good luck in your quest and all the best, at the various hurdles.
Better - to be safe than sorry, as the saying goes.
Take care.

I am unable to answer enquiries concerning objects, which are NOT related to the areas of Fine Art and Antiques. Nor will I; on the sole basis of any photographic images be willing to give any definitive monetary valuations, or monetary opinions. In such cases I would always advise on getting “real time” valuations and opinions from reputable and qualified auction houses, or third parties. In some applicable cases, I may perhaps give general indications of value, based on the presented materials. True valuations always need a direct “hands on” approach, with perhaps also the necessary research and verifications. Broadly open to almost all questions, regarding the majority of both European, American quality objects, which are related to both Antiques and Fine Art. This also includes modern 20th century designer objects such as furniture etc. My own particular comfort zone areas would be; The decorative Arts, marble, stone, furniture, ivory, bone, amber, ceramics and porcelain, sculpture, glass, silver and metal objects etc. I will also answer inquiries, and give opinions concerning Dutch 17th, 18th and 19th century paintings. Please note that I do have limitations and cannot possibly answer all questions, as the field is very extensive. VERY IMPORTANT and PLEASE NOTE: Please note that; providing > GOOD CLEAR and Preferably High Resolution < photo's of the object(s)in question, is vital. Pics taken with a cell/mobile phone, are of a poor quality and best avoided. Posting signatures only, or just fragments of an artifact - will only provide me with insufficient information and it is often quite misleading. So please; Do post good clear overall images, with your question(s). Failing to do so, may cause rejection, which is also a great pity.


Since the early 90’s I lead a team of very enthusiastic staff at a business, where have the following disciplines; Restoration and refurbishment of historical buildings and gardens, including interior design. The restoration and care of Fine Art and Antiques at our restoration studio We are also Fine Art and Antique dealers, besides being collectors ourselves for a great number of years.

Villa Rufolo; The forgotten paradise on earth. Published by the University of Aarhus, Denmark Book reviews and articles for International Archis Magazine, in the Netherlands.

Since I wished to become a Restoration Architect, firstly I took my BA degree in Art History. Then after graduation, I followed this immediately by studies to graduate and become a Restoration Architect. Ever since then, I have been an established Restoration Architect and Antiquarian. Since a great number of buildings are also inhabited by Fine Art fixtures and furnishings, I also became absorbed by all the artifacts, which go to fill them and not only the edifices themselves. This and much more, was the reason for gaining an advisory post on the City Commission; For The Protection and Care of Historic Monuments of Amsterdam - Amstelveen.
