The claimed Voynich page

[Jorge_Stolfi]

But in this case, what fun would there be in making an improved copy of the plant with minor changes to the text, for what fun? The parchment shows a purpose of realization that is still unknown to us and labeling it as "fun" seems to me the most convenient solution to say "I don't know what it is, therefore it's a joke."

I don't think it was meant as a joke.  I would compare it to the porcelain statuettes that Koen's wife made of the bathing nymphs and showed at the last Voynich Day conference.  Again, I think that someone who was fascinated by the manuscript wanted to make a facsimile of a page as an art project; but cared more about the image than about the text, so he/she improved the former and did only a quick job on the latter.  We can see that the text is "crude" and "crooked", but to a "layman" it probably looks as good as the original.

Several years ago a student of mine went to a conference in Egypt and brought me this tourist souvenir (unframed):

   

The support seems to be real papyrus, but of course made "industrially" in the present.  From fifty yards away the artwork looks superficially ancient Egyptian style, but from ten yards one can already see that the details of line style and painting technique are totally modern. And besides it has the artist's signature at the bottom.  And it is printed, not drawn, of course.   The drawing must have been copied from some ancient original -- perhaps a mortuary mask on a sarcophagus -- but surely with plenty of "artistic liberties".  The artist obviously did not intend to make an accurate reproduction of it, but only a good-looking picture with "ancient Egyptian look and feel".

I think it is very much like the way that VMS plant was "copied" in your page. 

All the best, --stolfi
