I think that is more likely.
There is one very odd thing though.
The reverse has a wax seal (just as a stamp - it does not seal anything) with the initials A.G.
This matches (coincidentally?) Aldo Gritti.
That is more than weird. (Best Google for this name).
However, I definitely do not suspect Fabrizio Salani of any involvement in that.
He really hopes that this dates back to Prague and spent some money to have the materials tested.
The parchment has not been dated - at least not that I know - as that would be very expensive.
