I considered this too, given that at first glance it's a Cenedese-esque sig but on reading it you could fit 'Venini' into the letters. But I thought that, on reflection, the hand that signed the piece probably looked a little too assured to be a casual faker.
That, and the brain's a funny old place when confronted with apparently random data - finding patterns and messages in it that simply don't exist.
But... pretty much every fake sig I've ever seen has been a grotesque childish scrawl. So if it were by a professional faker, experienced with engraving glass, you would've thought they'd have at least made it legibly like an existing signature.
