My initial reaction was "no chance" too, BUT:-
There's the streak of iridesence - absolutely correct
The coach-bolt pontil mark
The swirl pattern was used both at Mdina and in the very early experimental days of IoWSG.
The colours are correct. This blue is the shade used in the strapped aurene pieces - it may look a little dull - but it's mixed a bit with the ambers and ochres.
The WAY the colours work together to create the design, as a whole, is absolutely spot-on perfect.
(try examining these pink and blue swirls in close-up!)
But it is a very funny shape.
