And like you, Sue, 'Pressed glass from Murano' sets off a warning bell!
(I tell lots of sellers to ask for info on GMB but very often they don't do it, sorry to have been pre-emptive in this case)
Surely this item is identifiable, whether the label is right or not? It looks to be well made and if you made a press-mold then you would have made at least a few hundred of them, while the mold was set-up? We need a specialist cat collector?
