Culture Vulture, that would just be perfect

sadly, I think completely unlikely, however the 'tone' of the facial expression is remarkably similar a sort of cheeky expression.
Frank, I have to confess I see the word 'faux' and it makes me nervous

what is this faux paint? I think with the texture of the face, there are so many lines that either it would have had to have been done with a textile of some sort as Sue suggested or with a wire paint brush or something, in order to get the number of lines and crisscrossing if you see what I mean. I've looked again at the dimples on his cheeks and I think they were made by dropping lumps of frit/stones onto the glass then cased over which created the bubble on top of the stones (which, I think, I can see under a strong magnifying glass deeper towards the base of the piece). The eye bubble is just a bubble then with what looks like a drop of blue glass dropped into it and the line of dark glass/ink/faux paint behind it.
So, is it a 'kind of' graal technique then?
