How to Check if a Museum Image Is Really Public Domain
Where The Met, the Rijksmuseum and the Smithsonian state rights, what "believed to be public domain" actually tells you, and why the answer can change at the border.
Quick answers
- Where does The Met say an image is public domain?
- On the object's page on metmuseum.org, open access works carry a Public Domain label near the image with a download option. The Met's collection API marks the same objects with isPublicDomain set to true.
- Does public domain in the US mean public domain everywhere?
- No. The US mostly counts from publication date, and as of 2026 works published there before 1931 are public domain. Much of the world counts from the artist's death, often 70 years, and a few countries use longer terms.
- Is a photo of a public domain painting also public domain?
- The photo can be a separate question from the painting. US courts have held that a faithful photo of a flat public domain work adds no new copyright, and EU law now says the same for reproductions of public domain visual art. Photos of three-dimensional objects can carry their own copyright. A museum CC0 release covers its own photo either way.
"Public domain" sounds like a yes-or-no answer. In practice you're checking three things: what the museum says, what's actually in the picture, and where you plan to use it.
Step 1: find the museum's own statement
Always go to the museum's object page, not a copy of the image somewhere else. Here's where each of our three sources puts it:
| Museum | Where the rights are stated | What to look for |
|---|---|---|
| The Met | Next to the image on the object page | A "Public Domain" label and a download link. The API field is isPublicDomain. |
| Rijksmuseum | With the image on the object page | The rights statement and a download option. The collection data carries a Creative Commons URI. |
| Smithsonian | Under the image on collections.si.edu | A CC0 label. The Open Access API marks the record's usage as CC0. |
Every work page on Musist quotes that statement word for word, links to the object page, and says when we last checked it. The museum's page is still the one that counts. Rights statements do get updated.
Step 2: read the wording carefully
Museums hedge, and they're right to. You'll see phrases like "believed to be in the public domain" or "to the best of our knowledge". That's the museum telling you it did its homework, not that it guarantees the result. It also means the museum isn't taking on your risk.
What the museum's CC0 release definitely does is waive whatever rights the museum itself has in its photograph. That matters, as the next step shows.
Step 3: artwork versus photograph
There are two layers in any museum image:
- The artwork. Public domain once its copyright runs out.
- The photograph of the artwork. A separate thing, taken by the museum or someone it hired.
For flat works like paintings, drawings and prints, a faithful photo usually adds nothing new. A US federal court said so in Bridgeman v. Corel (1999), and the EU's 2019 copyright directive says reproductions of public domain visual art can't get new copyright. Photos of sculptures, furniture and other 3D objects are different: lighting and angle are creative choices, so the photo can have its own copyright. A CC0 release from the museum covers that layer too.
That's why the source matters. The same painting downloaded from a stock site or a publisher's website can come with terms the museum's version doesn't.
Step 4: public domain where?
Copyright terms are national:
- United States: mostly based on publication. As of 2026, works published before 1931 are public domain. Unpublished works follow different rules.
- Most of Europe and many other countries: life of the artist plus 70 years.
- Some countries run longer. Mexico uses life plus 100.
So a painting by an artist who died in 1950 could be fine in one country and protected in the next. Museums mostly state their position under their own country's law. If you sell worldwide, the strictest market you sell into is the one to check.
A five-minute check
- Open the museum's object page. Find the rights statement.
- Note the artist's death date and the work's date.
- Is it a flat work or a 3D object? Download the museum's own file either way.
- Think about where you'll sell.
- Save the page link and the statement with the date you checked.
