From the site: "Each of the 10,000 unique NFTs corresponds to an original work on paper by Damien Hirst. The collector has to decide between the digital NFT or the physical artwork, but can not keep both. This exchange is a one-way process, so choose carefully.
Two months after the NFTs are allocated, collectors will get the opportunity to exchange the NFT for the physical artwork. You have until 3pm BST 27 July 2022 to decide to keep either the digital NFT or the physical artwork. Similarly, if you have exchanged it in that period, the NFT will have been destroyed.
There will be an exhibition of the artworks before they are ultimately destroyed."
