Italian or Venetian or Just Rubbish ?

Definitely not rubbish. There's still good demand for pieces like this, especially blue.

I would say it's Bohemian in origin and not terribly old, maybe 70s? I have to admit to a bit of laziness in that I never bothered to research this type of glass because I didn't have to. It was always an easy sell.

If keeping for yourself, display it (not around little kids or pets). It's all hand decorated and just lovely (IMHO).

 

I'd have figured it for Italian with those flowers painted on, but the two must have been trading design influences since the Roman Empire.

 

I would guess Venetian.

 

I thought Bohemian as well. The awkward base makes me wonder if it had a stand of some sort. Its gorgeous.

 

Both Bohemia and Italy had and have makers of this stuff, flowers included. That cobalt, the bowl shape and the criss cross is slightly more indicative of Bohemia, I'd say.
