Elaine Hu wrote an informative article on Cointelegraph regarding NFT’s (Non-Fungible Tokens) and expiring copyrights. On one hand, NFT’s can be an important source of revenue to heirs rights holder of expiring contracts, allowing them to exclusively mint works and continue to collect on them after the copyright expiration. On the other hand, NFT’s can also be a gold mine to public NFT creators once works expire and enter public domain.
