How can cost this picture?

[Деко]

Daria Nikolaevna, I disappoint you somewhat, apartment for this picture can not buy. The layers IPE did, even their very famous in Europe, but they are always branded with the exception of the period 1814-1825gg. Done in large numbers and layers of Berlin Royal Manufactory, but there is also always stood stamp - squeezed in a test scepter.
The layers of this size and the period is always going unglazed on the reverse side. In addition, their edges slightly rounded on the perimeter. And they are less in thickness.
Your object is really more like a ceramic tile. Not very old. If you still find that the printed image - cost will be only frame.
