But I don't understand why you want this, except as a way to gull your audience out of money.

I have rather a lot of original art, partly because I was involved with a New York City art gallery for several years.

I own the actual works. Some of them hang on our walls at any time, and we rotate them.

What value is an NFT to me? It doesn't prove I own the art, it doesn't contain an image of the art, it doesn't serve any actual purpose.
