Digitisation absurd watermarks: what to do with them ?

[Jean-Baptiste-Camps]

Do we agree that such absurd watermarks as,

need to be tagged as DigitisationArtefactZone (even if a digital artefact, as opposed to a ruler or color card)? Or ignored altogether as noise ?

Personally, I'd ignore them as noise. In fact, the example isn't actually part of the actual image in the archive.org dumps but situated in a separate overlay that can actually be filtered out.
