Define, please, the price

[vit]

Thank you, Kirill for the hammer. Indeed - "As they say, the taste of any client's interior designer." Engravers turning over in their graves: (The hammer is so omnivorous, they expose even the student's drawings and performances. Often mediocre. (At home, I have a sofa piled high, my student, much more interesting sketches).
But seriously, (God be with them, with the atlas) is something I have not come across it names lights Russia engravings. (Wortman, Chemesov, NI Utkin, Afanasyev, Zakharov, Pozhalostin and so etc.). I do not have all the information, but can be a bit not the level of the auction?: Shy:
Could you, if possible, to provide price guidance on the above authors ???
