It gets complicated. Some of the other comments address this with some good suggestions. On the NFT listing itself, this is also addressed with the following info:

"If purchasing on the secondary market (i.e. not the original purchaser acquiring the art from Phygital Artform) you may also be eligible for a free canvas print provided a minimum royalty fee was distributed to Phygital Artform during the secondary market sale, which is dependent on the price for the secondary market transaction. Full details on how to redeem are unlocked for the acquirer of this NFT."

The NFT was programmed with ongoing royalty payments to the original creator on additional sales. The assumption was the royalty would cover the cost of the physical artwork. But it does remove some of the uniqueness. Much has changed in the NFT landscape since this article was written in any case! Thanks for reading.
