Anatoly Shary, I do not know where it is the assertion that such work should (must) bear the stamp "reproduktion".
Do not argue, you know better.
The maximum price for the work of the mid-19 th century and a similar technique that I saw in Europe was 400 euros.
It was a Flemish still life 17-th century in good state of preservation and excellent technical performance of the mid-19 th century.
"Aus Beckers Kunstverlag München"
Aus=on /of
Beckers = name (name of the company by the name)
Kunstverlag = Kunst = Art, Verlag = general name companies that produce printed materials.
In this case, specifically "Print works of art"
München = geographical definition, where the firm.
If you want to know whether this company is something special, like Faberge?
Answer: no.
