most of the work here (https://www.behance.net/dotlineform) is for sale...
signed editions: printed and mounted/framed. mounted on an aluminium frame, dibond, conventionally framed, or simply a print. I use Spectrum Photographic for edition printing.
unlimited editions: smaller sized prints (e.g. 20 x 20 cm), unframed. also available as digital downloads for you to print or save as you wish.
NFTs: happy to produce something related to a specific work, packaged as an NFT on a respected market place.
there are always lots of options...
