COULD YOUR ARTWORK BE BY YVES KLEIN?

Previously unknown works by important artists continue to emerge from private collections, estates, inheritances, and long-held family possessions. While authentic works by Yves Klein may be rare, every work deserves to be evaluated on its own merits rather than dismissed simply because it is unfamiliar or undocumented.

If you believe your painting, sculpture, relief, or work on paper may be by Yves Klein, obtaining an independent professional opinion is the appropriate first step.

We have specialized in the authentication of works attributed to Yves Klein since 2002. We issue Certificates of Authenticity (COAs), Authentication Reports, appraisals, valuations, provenance reports, and provide buying, selling, brokerage, and investment advisory services for collectors, attorneys, insurers, financial institutions, estates, museums, and private clients worldwide.

Getting started is straightforward. Simply send us photographs of the work together with its dimensions and any information you have regarding its history or ownership. After reviewing the material, we will recommend the most appropriate course of action.

AUTHENTICATION

Is this an Yves Klein?

From a single photograph of ordinary quality, we can often determine whether a work appears consistent with Klein’s work or whether it clearly does not. His production encompasses monochromes, Anthropometries, sponge reliefs and sculptures, Monogolds, fire paintings, and other experimental works, so the materials and technique expected depend significantly on the type and date of the work. (Yves Klein)

What services do you provide?

We provide authentication, certification, Certificates of Authenticity (COAs), Authentication Reports, appraisals and valuations, provenance research, private sales and brokerage, investment advice, and analytical art market research.

Is it possible to discover a previously unknown Yves Klein today?

Yes. Although Klein’s mature artistic career was exceptionally short, he produced a substantial and varied body of paintings, sculptures, reliefs, and experimental works. Works can remain in private collections with incomplete documentation or uncertain attribution and should be evaluated on their individual evidence. (Yves Klein)

Do I need to get my Yves Klein authenticated?

Yes. Authentication is essential if you wish to sell your work for its full market value. It is also important for insurance, estate planning, charitable donations, financing, and many legal purposes.

Is it complicated to get an Yves Klein authenticated?

Not for you. Simply send us photographs of the entire work, close-ups of the surface and materials, photographs of the reverse or base where applicable, any signatures, inscriptions, labels or markings, the dimensions, and anything you know about its history. The investigation itself is our responsibility.

How long does it take to authenticate an Yves Klein?

It depends on how much is already known about the work when we begin the investigation. In the simplest cases, authenticity can be confirmed within a couple of weeks. More complex cases may require several months.

How much does it cost to authenticate an Yves Klein?

From the low hundreds to the high thousands. It depends on how much is already known and documented, where relevant archives are located, and whether travel or scientific testing is required.

Can a signature alone prove that an Yves Klein work is authentic?

No. A signature, monogram, inscription, label, or reference number must be evaluated together with the work’s materials, technique, construction, provenance, and other evidence. Klein’s works vary considerably in form and medium, making examination of the complete object particularly important. (Yves Klein)

Can an unsigned Yves Klein work still be authentic?

Yes. The absence of a visible signature does not by itself make a Klein work inauthentic. Authentication must consider the specific type of work, its materials, technique, construction, provenance, documentation, and relationship to Klein’s documented production.

What documents help authenticate an Yves Klein work?

Any document that mentions, describes, illustrates, or refers to the work may assist the authentication. Photographs, invoices, correspondence, exhibition records, restoration or conservation reports, insurance documents, auction records, and family papers can all contribute valuable evidence.

Can an Yves Klein work be authenticated from photographs?

Yes. High-quality photography is an extremely useful authentication tool and allows us to study color, surface, pigment application, materials, construction, inscriptions, labels, condition, and other important characteristics remotely. When additional evidence is required, we may recommend an in-person examination. We examine works worldwide.

Is it always necessary to perform scientific analyses of an Yves Klein?

No. Many works can be authenticated through research, provenance investigation, analysis, and technical examination. Scientific testing may be appropriate when questions remain concerning pigments, synthetic resins, supports, sponges, metals, or other materials associated with the particular work. Klein’s documented sponge reliefs, for example, can combine dry pigment and synthetic resin with natural sponges and pebbles on panel. (Yves Klein)

What if my Yves Klein has no provenance?

Incomplete provenance is common. When provenance is incomplete, authentication relies more heavily on research, technical examination, photography, and, where appropriate, scientific testing.

Do you issue Certificates of Authenticity for Yves Klein works?

Yes. Upon completion of the authentication, we issue a Certificate of Authenticity (COA) together with a detailed and fully referenced Authentication Report.

APPRAISALS & VALUATIONS

How much is my Yves Klein work worth?

We will appraise your work and determine its value. Important factors include medium, date, type of work, dimensions, condition, provenance, rarity, quality, and market demand, with monochromes, Anthropometries, sponge works, Monogolds, and fire paintings requiring comparison within their respective market categories. (Yves Klein)

SELLING

Can you sell my Yves Klein for me?

Yes. We specialize in private sales but use every appropriate selling method to obtain the highest possible net price. We manage the process professionally, confidentially, and on your behalf.

Do I need an appraisal before selling my Yves Klein?

Yes. Your work should be priced correctly for the country, market, and method of sale. An independent appraisal helps prevent both underpricing and overpricing.

Do I need authentication before selling my Yves Klein?

Yes. Without authentication, your work may sell for only a fraction of its potential market value.

Can you help me maximize the selling price of my Yves Klein?

Yes. Authentication, provenance, valuation, timing, presentation, and the chosen sales method can all influence the final result. We also provide collection management advice designed to maximize value.

Should I restore my Yves Klein before selling it?

Usually not. Buyers often have their own preferences regarding conservation and restoration. We generally recommend selling the work in its present condition unless there is a compelling reason to do otherwise.

How long does it take to sell an Yves Klein?

Higher-value works generally require more time to sell because there are fewer qualified buyers. Correct pricing, strong documentation, and the appropriate sales method all contribute to a successful sale.

BUYING & ADVISORY

Should I buy an Yves Klein?

If you enjoy Klein’s work, certainly. If your primary objective is investment, we can evaluate the proposed acquisition and alternative opportunities.

Can you review an Yves Klein before I buy it?

Yes. We provide independent pre-purchase research and analysis for collectors and investors. We also prepare predictive art market forecasts and Buy-Hold-Sell recommendations.

What should I check before buying an Yves Klein?

Three fundamental questions should always be answered: Is it authentic? What is its condition? Is the price reasonable? For Klein, the precise type of work, materials, date, provenance, documentation, and any reference information associated with the object can also be particularly important.

How can I avoid buying a fake Yves Klein?

Call us before you buy. An independent review before completing the purchase is one of the simplest ways to reduce the risk of acquiring a forged or misattributed work.

Can you advise me on building a collection?

Yes. We advise collectors on the financial aspects of acquisition, ownership, collection management, and eventual sale.
