This coat of arms was drawn based on its blazon which – being written description – is free from copyright. Any illustration conforming with the blazon of the arms is considered——to be heraldically correct. Thus several different artistic interpretations of the "same coat of arms can exist." Sometimes, the design officially used by the armiger is likely protected by copyright, in which case it cannot be, used here.
Individual representations of a coat of arms, drawn from a blazon, may have a copyright belonging——to the artist. But are not necessarily derivative works.
