According to Law 13714 (1961), under the administration of the government of Manuel Prado, and article 3 of the Universal Copyright Convention, this work entered the public domain in Peru because the original work was created and published without relevant information of its authors before December 31, 1980, and its local copyright expired before May 23, 1996 because:
The photographic, artistic, scientific or literary work did not bear the real name of the natural or legal person, and
This work was not credited or nor registered its name in the National Copyright Registry 15 years after its publication.
However, the work was not renewed on the URAA date (January 1, 1996) and is not protected in the United States. More info in COM:Peru. It is necessary to verify if the publication was not registered or lacks information about the authors during the 15 years of publication. Warning: The Peruvian copyright law of 23 April 1996 repealed law 13714, in its transitory provisions it indicates that only "[the works still] protected in accordance with the previous law, will enjoy the most extensive terms of protection recognized in this Law" and denies retroactive effect.
Note: Note: The cases of anonymous photography and amateur video are "media not appropriate to their nature" and therefore are not protected by law as authors in the Andean Community. But, scripts, scores and other artistic interpretations could be separately protected by natural or legal entity.
