We don't know. There are a few out there.
You have to consider there was only so much work he could have done in the short 3 years he was at Mdina, he had to get good enough to make such a complex and big thing. He did not like signing things. He felt the art should be able to speak for itself. (personally, I agree.
) He only did it when asked by the buyer, or for export to the States, where they sort of insisted on it.
I believe that there were certain items he did sign in a small experiment to see if they sold better, which may have overlaped a bit with the American import insistence.
Those tend to be Ice-Cut Lollipops and Japanese Globes.
So finding a signature on an Ice-cut Lollipop he made is not entirely unexpected.
The really unexpected thing is finding an Ice-Cut Lollipop he made at all.
We have tried to count some of the scarcer things. I think we're up to there being around 40 Crizzle Stones known, and around 9 teal-strapped Amethyst "Club" bottles.
I imagine there are more Ice-cut Lollipops than Crizzle Stones, which are still considered to be one of the scarcest and most desirable pieces.
There are others here who know lots about Mdina, Mark is happy just to leave it to us.
The whole purpose of the board is to discuss and find answers to questions about glass. Without questions, there is no point in us being here.
Please, carry on!
