COULD YOUR ARTWORK BE BY JOAN MIRÓ?

Previously unknown works by important artists continue to emerge from private collections, estates, inheritances, and long-held family possessions. While authentic works by Joan Miró 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, drawing, print, sculpture, or ceramic may be by Joan Miró, obtaining an independent professional opinion is the appropriate first step. Miró worked extensively across painting, drawing, printmaking, sculpture, ceramics, illustrated books, and monumental commissions.

We have specialized in the authentication of works attributed to Joan Miró 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 a Joan Miró?

From a single photograph of ordinary quality, we can often determine whether a work appears consistent with Joan Miró’s work or whether it clearly does not. His production spans paintings, drawings, prints, sculpture, ceramics, and illustrated books over many decades, so medium, period, materials, and technique must be considered together.

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 Joan Miró today?

Yes. Miró was highly prolific across numerous media, and previously undocumented paintings, drawings, prints, ceramics, sculptures, or related works can still emerge from private collections and estates. His studio also contained works that had remained unseen at the time of his death.

Do I need to get my Joan Miró 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 a Joan Miró authenticated?

Not for you. For paintings and works on paper, send photographs of the front and reverse, close-ups of the surface, signature or inscriptions, labels, and edges. For sculpture or ceramics, send photographs from several angles, including the base, surface, signatures, inscriptions, edition information, and foundry or workshop marks where present. The investigation itself is our responsibility.

How long does it take to authenticate a Joan Miró?

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 a Joan Miró?

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 a Joan Miró painting is authentic?

No. A signature or inscription must be evaluated together with the painting’s materials, technique, support, date, provenance, and relationship to documented works by Miró.

Can an unsigned Joan Miró painting still be authentic?

Yes. The absence of a visible signature does not by itself establish that a painting is inauthentic. Authentication depends on the work as a whole, including its materials, technique, support, date, provenance, and other physical and documentary evidence.

What documents help authenticate a Joan Miró painting?

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 a Joan Miró painting or drawing be authenticated from photographs?

Yes. High-quality photography is an extremely useful authentication tool and allows us to study paint application, line, surface, support, paper, signatures, inscriptions, 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 a Joan Miró?

No. Many works can be authenticated through research, provenance investigation, comparative analysis, and technical examination. Scientific testing is generally reserved for more difficult cases when questions remain concerning pigments, binders, canvas, paper, inks, ceramic materials, bronze, patina, or other components.

What if my Joan Miró 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 Joan Miró 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 Joan Miró worth?

We will appraise your work and determine its value. Medium, period, subject or composition, dimensions, condition, provenance, rarity, edition information where applicable, and current market demand are important factors, while paintings, drawings, prints, sculptures, and ceramics must be valued within their respective markets.

SELLING

Can you sell my Joan Miró 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 Joan Miró?

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 Joan Miró?

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 Joan Miró?

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 Joan Miró 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 a Joan Miró?

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 a Joan Miró?

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

Can you review a Joan Miró 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 a Joan Miró?

Three fundamental questions should always be answered: Is it authentic? What is its condition? Is the price reasonable? For prints, also verify the printing technique, paper, impression, signature, numbering, edition, printer, and publisher; documented Miró prints include lithographs, etchings, and aquatints issued in specific editions.

How can I avoid buying a fake Joan Miró?

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.
