Our position on this issue fully corresponds to the official position of Wikimedia.
All images on our website are accurate photographic
reproductions of original two-dimensional works of fine art.
The works of art themselves are in the public domain in those
countries where the term of copyright protection is equal to the
life of the author plus 100 years or less.
This concerns the legislation of the United States and many other countries.
Photographic reproductions of two-dimensional works of art that
are in the public domain are also public domain.
We proceed from the premise that all our images are photographs
of works of fine art, whose authors (Old masters) lived until the
beginning of the 20th century.
Consequently, all images of our site are in the public domain and
are free from copyright restrictions.
