There is an idea associated with the art

But if the work had never been shown, theoretically, holders may require the removal from the exhibition and its destruction, for example, its reproduction in the catalog of this exhibition, and I confess that when I wrote my message, I had in mind precisely this situation.

I perfectly understood what was discussed in your message, just explained that there are no misunderstandings.

And, this is strange: «In the case of already released a picture - at least in France - the rights holders can not prevent its publication by a third person, they can only seek monetary compensation ...»
Perhaps we are talking about the publication for informational purposes. Otherwise, the question arises: the place of publication, Circulation, amounts, dates, etc. on the fact of what happened.
You can ride a one-time publication of the image so that it will long be used by any other potential buyers. Question arises profits.
The artist, in 20 years, wrote a scene that he himself badly ndravilas, but ten years later, became annoying. Surely he has no right to prohibit its publication (play) just because it was published, and is doomed for life to blush for a fee? Once, not just the French. Although the possibility gulnut once in 2-3 years for 18-20 euro - tempting.

Perhaps, but I said, «almost not to infinity.

In the 10-25-year terms were tricks that allow, under certain manipulations that transform into perpetuity. There was some confusion with the related rights, the rights of citizens and organizations, economic and moral, etc.
With repressed by the authors do not know what to do, Toli forget about them, Toli confer rights from next year after a year of full rehabilitation. It turned out that some public works retroactively became protected.

In any case, the uniqueness of the introduction of "50 (70, thanks for the clarification) years after the death of the author" (and not from the first-last publication, previously promulgated, unpublished; lifetime, posthumous) allowed publishers to properly orient in space and time .

In addition to the protection of the rights of authorship VAAP engaged and creative unions (Union of Artists, writers, composers ....).

In short, not so simple. There was a quiche-mis in the republican laws, that my head will break. Composer of the Kyrgyz Republic, a poet from Estonia and the singer from Georgia protected in different ways, it is true yet I still guarded properly. Here, from the same place:

«The ability to set specific dates for the above categories of products used, not all Soviet republics, in particular, it is not envisaged in the legislation of the RSFSR, Ukraine, Armenia, Belarus, Kyrgyzstan, Latvia, Lithuania, Tajikistan, Turk ¬ menii and Estonia. Hence, there is photographic works and works of applied art shall be protected throughout the life ¬ or author and 25 years after his death.
In Azerbaijan, photographic works and works of applied art are protected for 10, Moldavia and Uzbeks ¬ camp-15, Georgia - 20 years. In Kazakhstan, the specific terms set only for photographic works (10 years) and for collections of photographs (15 years). Specific dates are calculated from the date of the publication categories of works considered by them to reproduce ¬ Denia, ie, apparently, for the photographs, since they were placed in the ne ¬ chutney production, and for works of applied art - from the mo ¬ ment, or their reproduction in printed or circulation ¬ tion in the industrial product.
