How can cost this picture?

[Дарья Николаевна]

Please tell me if it is done at the Imperial Porcelain Factory, then some sort of symbol should be. I've considered it now, again, nothing, but in the lower right corner, where the idea should be signed, as a bud with a knife to clean off. Great-grandfather lived in Tbilisi, bought the secondhand store, the check was not found. But he said that hard to sell, it can be to buy an apartment. It turns out he either was mistaken or had been deceived. And the question in general, and remains, the price of this product, if relying on the words of a specialist Magnum Ars that it was the 19 th century, how much can it cost?
