The only thing that I have that might be an MDG chalice is un-knopped, but it could also have been made at Mdina, un-knopped.
It's in the group photo I posted.
I have not seen any other potential MDG chalice, and certainly none with labels.
I know of perhaps another two attenuated bottles to the one I have, (there's one illustrated on Worthpoint) I have the only lollipop I've seen and the only tricorn bowl I've seen.
