painting to be a relative.
on any auction not set and no where is not for sale. theme created in order to find out at least the approximate cost of the painting.

That's the way it is ... habitual - "portrait".
  Well names, of course, such as that of your grandfather, too, there are. :)

Perhaps "The portrait of JF Evstigneeva."
Do not understand such a fuss about ordinary spelling.
JF Evstigneev, apparently, something is known, once received such a portrait?
davincho, you know?

Over 150 years of existence of the plant, it is included in the list of the ten best men of the plant.

The portrait of the gratitude of the plant.

Just a very even understand!

Gentlemen Well, in fact, as you can! Needless to say on the merits - so do not cling to anything or falling, just impossible to read! And what about the forum think newbies reading this, sorry, flea hustling on level ground? At the forum people turn for help, but instead of receiving such assistance so small bites! In personal relationships, then, none of this does not allow, but here goes, everything is possible. Adults are people, not to flirt!

So let the family stay! As a reminder the descendants of the skill and dedication. So I want to write - his grandfather.
... "I sold the home for the garage!" It was funny. And now, sadly.

I am not asking your opinion, what to do with the portrait.
Please write on the topic.

davincho, to get a portrait of big money, you can not. In the base map is the only landscape M. Kamanin, exhibited in the gallery with Shishkina estimate: 300-400 thousand rubles, but unsold. Estimate in no case should not fool you: landscape and portrait - two different things. The only option the sale of a portrait - a collector, passionately in love with the art of M. Kamanin and buy all of his works for any money, but I think that this unique landscapes you will not find.

With all the merits of the portrait, its main value - the family.

Well, do not. Option is not unique. Portrait of the man that came in the first ten factory workers for 150 years, should be of interest to the enterprise itself, its shareholders, owners, employees!
Or the union officials of the relevant professions.
davincho, tell me who was the grandfather of specialty (designer, accountant, turner?), And at what plant made its feats of labor?

Carpenter by profession. He worked at a factory, they are. Vorobyov, now Melinvest JSC, Nizhny Novgorod.

redbor, thank you, a good option.
But, I zutrudnyayus with the price!
