> How do you know a signed print is really from the artist?

you don't, that's partly why they are cheaper, that and there are more of them.

> If the provenance of that artefact can be reliably tracked over the years, then you can also be fairly certain.

This is why auction houses are a thing, its also why eBay are spending loads of cash with their verification services. They have provenance tracers, and "experts" who try to assert that something is "real"

> Obviously, a signed inkjet print can be forged more easily than a NFT,

Apart from looking at the specs, you can only embed the URL in the NFT: https://eips.ethereum.org/EIPS/eip-721 so the only thing thats really guaranteed is the URL and metadata. as soon as you download the NFT, it ceases to be the NFT anymore.

Signed prints are not necessarily cheap—see Ansel Adams prints going for nearly $1M USD[1]. It becomes a matter of what price society (or, perhaps just a handful of buyers) is willing to place on the artefact.

One of the great things with provenance on the blockchain is that it is not solely dependent on private for-profit auction houses like Christie's and Sotheby's to track provenance of the art we are creating.

By the way, NFT is programmable: it can define whatever you are willing to upload & embed onto the blockchain.

I'd recommend [2] if you are curious to understand this topic a little deeper.
