A match for the containers? 16th-17th century ivory vases

[JustAnotherTheory]

So much effort for a forgery—far too much effort.

Never underestimate a man with an obsession  

Having said that, the forgery could very well have been made by someone earlier than Voynich. Maybe someone who wanted $$$ from a well-known collector (something something Rudolf II).

The idea behind the forgery hypothesis remains the same, whether we're talking about 1912 or 1612.
