The concept of NFTs for art is pretty new. I first heard about the idea of NFTs in 2013 and that was using them for things like deeds to land and vehicles.
which is incredibly stupid because a nft is fundamentally incapable of solving these challenges (owning the nft means nothing if a court determines someone else owns the house)
... which remains a terrible idea, because what happens to your land or vehicle if you lose your keys / forget your pass phrase? Or if someone else phishes you?
