Want to Sell Joan Miró Prints? Begin by identifying the exact work and edition. A signature, number or familiar image alone does not establish originality. Our gallery reviews the technique, paper, dimensions, inscriptions and documentation when considering a work for direct purchase.

Original Edition, Pochoir or Reproduction?
Miró imagery appears in several forms. The word “lithograph” on a label, a printed signature or an old frame is not enough to identify which version you own.
| Type of work | What to check |
|---|---|
| Original graphic edition | A lithograph, etching or other work created as graphic art. The physical impression should match the documented edition. |
| Unsigned publication work | Some original lithographs were issued unsigned in books and publications. Identify the exact publication and version. |
| Original lithographic poster | Some exhibition and event posters are original lithographs. Check the printing process, lettering and recorded edition. |
| Constellations pochoir | The 1959 publication includes 22 pochoir reproductions after gouaches, separate from its accompanying original lithographs and etchings. |
| Later reproduction | A copy of an existing image, such as a modern decorative poster or digital reproduction, requiring a different description from an original graphic edition. |
Check the Catalogue Reference
Miró’s graphic works are documented in several reference systems:
- Mourlot / M.: lithographs.
- Dupin / D.: etchings, aquatints, carborundum and related engraved works.
- Cramer Books: illustrated books and publication projects.
One sheet can have both an individual-work reference and a publication reference. A catalogue entry identifies the documented work; it does not authenticate the physical impression by itself.
Distinguish Handwritten and Printed Signatures
Many Miró editions were signed in pencil, but the expected inscription varies by work. Compare the signature’s form and placement with the recorded edition.
- Hand-signed: a signature added individually to the impression.
- Printed or signed in the stone: a signature reproduced within the image, rather than added individually.
- Unsigned as issued: no individual signature was required for that documented version.
A printed signature does not automatically make the underlying work a reproduction. For books and portfolios, a signature on the justification page does not mean every sheet was individually signed.
Read Edition Numbers and Proof Inscriptions
A fraction such as 27/75 identifies an impression within an edition; a Mourlot or Dupin number identifies the work. E.A. denotes an artist’s proof, while H.C. means hors commerce. Roman numerals can identify a separate edition or proof group. Each inscription must correspond with the specific edition; none independently proves authenticity.
Compare Paper, Dimensions and Publication Details
Check the sheet and image measurements, paper, margins, watermarks when documented, and printer or publisher information. Trimming, mounting and restoration can obscure identifying details. For poster projects, the presence or absence of lettering may distinguish different versions of the same design.
Gallery invoices, auction records, collection labels and estate documents can support the ownership history. Keep these with the artwork, and compare their descriptions with the physical sheet.
Initial Review and Formal Authentication
The Fundació Joan Miró describes a formal authentication process for graphic works that requires direct examination. Our preliminary gallery review helps identify the edition and assess a potential purchase; it does not replace formal authentication or constitute an authentication certificate.
Photographs and Details to Send
- A full photograph of the front and a photograph of the reverse.
- Close-ups of signatures, numbering, proof inscriptions, stamps and labels.
- Sheet and image dimensions, when accessible.
- Purchase records, ownership history and any catalogue references.
- For books or portfolios, the title and justification pages, all sheets and original covers or case.
Leave framed artwork in place for an initial inquiry. If you can only measure the frame or visible opening, tell us which measurement you are providing.
Once the work has been identified, explore our Miró value guide and selling process.
Frequently Asked Questions
Does an unsigned Miró have to be a reproduction?
No. Some documented original editions were issued unsigned. The printing technique and publication details must still match that version.
Does a certificate prove my Miró is original?
A certificate should be assessed by its issuer, scope and connection to the specific artwork. It does not remove the need to examine the sheet and its documentation.
Can you begin reviewing a framed work?
Yes. Send the photographs and measurements you can obtain without disturbing it. We will explain whether further examination is needed.
