The painting, signed by Grigoriev
 

A small picture on the cardboard (where some 10 to 22 cm), signed on the back Grigoriev.

Cyril Syzranskiy, show you if you can, what kind of artist performed this work and for how much you can sell.

Yes, the puzzle you asked Cyril Syzran!
The site artru.info counted 68 artists Grigoryevs ......

I understand perfectly the complexity of this task. I hope the experience and knowledge of Cyril.

They can only add that this work is among other got me from a collector from Astrakhan. That is, it can be Grigoriev, who worked in the Volga region ...

 We must look for is among the 67, because this is clearly not Boris Dmitrievich. The task easier ...

Strange some Grigoriev.
Oil painting, wrote, and "signed" with a pencil ... Paints ended?

Can not he, but the collector has signed this job?

It vozmozhno.Takie sketches artists often do not podpisyvayut.Interesno what period работка 50,60 years?

Excuse me, but where do you work? Nothing personal, just in time "hits" on the cheap auctions or random sources for these works - the pencil signature, even almost a standard, but the "non-core" work - oil, gouache, etc. - In the end with a sad smile, museum workers reported that in my hands fufel. On error learning ... Since such signatures in my very biased. All the best!

Peter, if you look closely, then on the back of the picture in the top corner written - 1956

No, it does not work with the auction ... I got it "a load" among other sketches by purchasing the work of a collector from Astrakhan.

Really!
I read and laugh!
