I want show you a paintings of Дубовской Николай Никанорович (1859–1918). It is made of oil on canvas and has size 24 x 32,5 cm.
The painting shows river Newa.

The painting has been sold for €3.000 in auction in Germany.

What I don't understand why this painting costs €3.000 and others €30.000 or more.

What is the reason for that?

Somebody who bought this painting is a lucky man?

What is your opinion on that? What is a value of this painting?

Thank you in advance.

best regards
