Somebody may well know, but not everybody logs in every day.
Normally, we'd bump a post after a month or so, rather than a few days,

but we do not give up here.
Sometimes id's are instant, sometimes they can take years.
This looks like a fairly contemporary Studio piece, but I can't make anything out of your pic of the signature. You could try rubbing a little talcum powder over it with your thumb, to bring it up for the camera.
You can post 4 images in each comment. Just click on the bracketted bit which says
(more attachments) under the browse button, and another box will come up.
I did think it looked a little like the work of Ioan Nemtoi, a great artist who is working on your side of the pond, but the signature doesn't
seem to be like his.
