Miniature portrait of lady - behind original convex glass

This lovely miniature portrait is partially framed - in original brass-edged holder,
and still behind original convex glass, but was most probably removed from wall hanging it was mounted onto.
(Please see photos for better explanation)

I am not sure how this picture was made, whether it is a water painting, or some other process which was used
to produce these pictures

It most definitely does not look like a print - I looked through a printer magnifying glass, which enlarges image 6 times, and there is no "pixels" visible whatsoever, which would be the case if it was a print.

It measures 8.5 cm X 6.5 cm, and is signed ET

Very pretty miniature with lovely detail
