I am not convinced by the provenance history of the VMS

[JustAnotherTheory]

Plus it's kind of weird how the Tepenecz signature would be so quickly "erased", when the manuscript, allegedly, is hundreds of years older than the signature and looks fine.

Anyway, I wonder if we can treat the folio with the Tepenecz signature as some kind of "crime scene" and use some visual forensic tools to investigate foul play. Something like multispectral imaging, ink analysis, chemical residues (for removing a signature quickly), fiber disturbance, etc... ? Although I admit that these tools are not available to us without a physical examination of the folio.
