Thanks for confirming the size of your vase. I have seen these over the years and don't believe it to be quite of the quality of Dino Martens work - although I understand why you made the connection.
That said, unfortunately I don't know the originator.
I expect someone with information on this will come along, but give it a little time as folks often pop by only from time to time.
Good luck with the quest

Nigel
