Pareidolia, but underwater: What is under the green paint?

[oshfdk]

I suppose if a model is trained on this folio it's possible to get much more curios results, but I was actually aiming for maximum certainty, so I only trained on samples from 6-7 folios and then applied the result to the whole MS. The main problem I have with automated pareidolia is the same I have with the natural one - the texture of the vellum itself provides a lot of subtle lines and curves, with enough squinting or tweaking of the parameters of models one can see/reveal almost anything.
