Walk the puzzle aisle and you will meet the same paintings again and again. Van Gogh’s Starry Night, Hokusai’s great wave, Klimt’s The Kiss, Vermeer interiors, Monet water lilies. Meanwhile you will almost never see a painting made in the 1980s. That is not a curatorial preference. It is copyright arithmetic.
Why the same paintings keep appearing
Licensing a copyrighted image costs money, requires a rights holder who is willing to deal, and adds a per unit royalty to a product that competes largely on price. Public domain images cost nothing and require nobody’s permission. A puzzle publisher choosing between the two is making a straightforward commercial decision, and the result is a catalogue heavily weighted toward art old enough to be free.
This also explains a quirk collectors notice: art puzzle ranges across competing brands overlap enormously, because they are all fishing in the same public domain pool.
How works enter the public domain
Copyright is finite, and the term depends on when and how a work was created. The United States Copyright Office’s FAQ on how long copyright protection lasts states that for works created after January 1, 1978, copyright protection lasts for the life of the author plus an additional 70 years. For an anonymous work, a pseudonymous work, or a work made for hire, the copyright endures for a term of 95 years from the year of its first publication or 120 years from the year of its creation, whichever expires first. For works first published before 1978, the office notes only that the term varies depending on several factors.
For older art the picture is cleaner. Copyright Office Circular 22, on investigating the copyright status of a work, states that works published or copyrighted prior to January 1, 1931 have expired and permanently fallen into the public domain in the United States. That single cutoff covers essentially every Old Master, every Impressionist, every Japanese woodblock print and most of what a puzzle brand would call fine art.
Two cautions. First, these are US rules; other countries calculate terms differently, which matters for a product sold internationally. Second, the same circular is candid that determining status can be complicated, and advises seeking professional legal counsel where a work’s publication date, authorship or registration is unclear.
Museum open access programmes
Knowing a painting is out of copyright does not hand you a printable file. For a long time the practical barrier was access to a high resolution reproduction, and museums controlled that. Over the last decade many have stopped.
The Rijksmuseum’s information and data policy is a clear example. It provides information and data that are no longer, or have never been, protected by copyright with a Public Domain Mark and/or the Creative Commons Zero 1.0 Public Domain Dedication. It explicitly does not distinguish between types of user: all users, including commercial parties, have access to the same information and data under the same conditions. Where the museum does hold copyright it says it will generally not exercise that right, and applies a CC BY 4.0 licence in the cases where it does. Attribution is framed as good practice rather than a legal condition, with the museum asking for a credit line and data citation regardless of the licence.
The practical effect for puzzle publishing is large. A designer can source a museum quality file of a public domain painting without negotiating anything.
Reproduction rights and the photograph question
Here is where it gets genuinely murky. The painting may be out of copyright, but somebody took the photograph of it. Whether that photograph attracts its own copyright depends on whether it is treated as an original work or a faithful record with no creative input, and jurisdictions differ on the answer.
Separately, museums have historically used reproduction rights and contract terms, rather than copyright, to control image use: you agree to conditions when you obtain the file. That is a different legal mechanism with a different scope, and it is one reason open access policies matter so much. They remove the contractual layer rather than the copyright layer, because the copyright layer was already gone.
Why the colours never quite match
Even with perfect rights clearance, a puzzle is not the painting. Several unavoidable steps intervene:
- The photograph is captured under particular lighting and colour balanced by a human making judgement calls.
- The file is converted to a four colour process gamut that cannot reproduce many saturated pigments.
- Ink sits on a coated paper liner rather than oil on canvas, so surface texture, impasto and gloss vanish.
- The puzzle is usually printed much smaller than the original, and detail scales down with it.
None of that is a manufacturing fault. It is the cost of moving an image between two very different physical media.
A note on scope
This is general background information about how copyright duration and museum image policies shape what ends up on puzzle boxes. It is not legal advice. If you are actually planning to reproduce an image commercially, on a puzzle or anything else, get advice from a qualified lawyer in the relevant jurisdiction before you print anything.
