### SIGIL SLICE

Collection owners can slice off a reinscription asset to create an individual original artist's *signed* limited print/edition. This is done with a delegate child inscription. These assets created only by the artist (collection owner) differ from the claimed delegate assets created by other people. Collectors may deem these as being more valuable and mimic the traditional art market.
