i'm fairly confident it's not Mdina,
except for :-
The colour is right but not the application of gold etc. having said that I did see a vase a while ago that had the application on the surface the same as I.O.W
but had a Mdina sticker on it.
So having shot myself down in flames I still think its not Mdina, :chky: :chky: :chky:
My gut feeling when I saw this and the other piece I mentioned is it looks like a cross over design. Just whistling in the wind here, but when M Harris was going from Mdina to I.O.W.
This vase has a bit of both in it.
Interesting to see the outcome of this
