The concept of "authorized appropriation" applies differently to old classic art depending on the copyright status of the original works. Many classic works of art, such as those created by artists who have been deceased for over 70 years, typically fall into the public domain. This means that these works are no longer under copyright protection and can be freely used by the public without needing authorization. Restrictions based on other factors: 1. *Reproduction Rights:* Even if a work is in the public domain, the reproduction of a particular photograph or digital image of the work may be protected by copyright. 2. *Moral Rights:* Some jurisdictions recognize moral rights of artists, which may persist even after the work enters the public domain, protecting the integrity of the work and the reputation of the artist. 3. *Trademark Law:* If the classic artwork has become a trademark or is associated with a particular brand, using it might infringe on trademark law. 4. *Cultural and Heritage Laws:* Certain cultural artifacts or artworks may have restrictions on their use based on national heritage protection laws. Therefore, when dealing with classic art, it's important to consider the specific legal context and any potential restrictions that may apply to the use or appropriation of the artwork.
