Farfalla is Italian for "butterfly".
We asked Italian collector Federico Croci about the two versions of
backglasses. He replies, "The 'uncensored version' is the usual version, it was sent everywhere in the world, not really in Italy only, and it's featured on the cover of the manual. Story is there was the USA distributor which was afraid about the
backglass, and asked it to be 'censored'. But it was produced only for him. So, the 'censored' version is rarer, as it was made for USA only. The graphic on the cover of the manual, though, remained the same. So, one really is the "international version", while the other is for USA only."
