signature Agnese Postempski 1858

If you have successfully dismantled a signature, because
the photo did not understand, then it may be Roman Postempski (1808-1858).
Here is an example of his work.
On Polish auction in 2008 it was estimated at 16,000 zl.:

This is most likely enamel (and not very bad).

Y Durer, have a similar story.

Madonna all have, but the plot is not quite that. In Durer is "Mlekopitatelnitsa (Nursing Madonna)."
Posmotrtie Domenico Tibaldi - Madonna on the crescent.

Most likely it is enamel (and not very bad).

What is enamel? Kidding?
    Painting on marble, and indeed very good.
 Although now the fashion-icon write on a stone,
but in the 19 century are extremely rare painted marble slabs in bronze frames.
At some auctions in Europe have seen similar. 2 or 3 thousand euros. I do not remember, was the author or not
