100 sheets of stolen vellum

[Fabrizio Salani]

This is interesting, because it means that whoever created the manuscript didn't care about the best graphic design or even the quality (regardless of their drawing talent). They wrote on both sides equally, like a travel notebook or a transcription of notes compiled during moments of rest or at the end of the information-gathering process. It's not a manuscript created for show, but for practicality. Forgeries usually need to be spectacular and highly decorated to attract attention.
