A Remarque is a small, original hand-drawn or hand-painted sketch added to a database item such as an Action Figure box, a Comic or Trading Card. It is most often created by the artist or otherwise related person like an actor or voice actor.
We add them to the database as variants to the non-remarqued item with the production status Custom. And like for Autographs the person that does the Remarque needs to have a direct connection with the item or otherwise be a renowned artist.
NOTE. A Remarque can also have an Autograph and in those cases should have both production statuses.
