The claimed Voynich page

[Koen G]

My best guess is that this was an attempt by a "VMS fan" to create a sort of facsimile, but with emphasis on beauty rather than accuracy.

I agree. Let's not forget that VM pages show up in all kinds of works of art (comics, video games...). It's a fascinating object. In this case, I'm thinking a prop for an (amateur?) movie project, a play or an exhibition. Something with a bit of a budget, motivation to make it look authentic, but also creative freedom. Since prop makers are creative types, the changes are easily explained. Artistic preference, more page-filling, balance... It also explains why old parchment was sourced and then cleaned.

Without further evidence, I think many options remain open, but at least to me it feels like a creative project. The addition of the wax seals makes me think of a prop rather than a fan's passion project.
