Sorry for the comparison, but , referring to other persons , it sounds like : " Of course , Mr. Pospelov - Larionov connoisseur , but to trust him with the purchase of the artist - is one thing, a connoisseur - it's different? " Like this ? It is not in the sense ernichanya , and for self-education. Really want to know. Thanks in advance .

(yes, there is some thing Larionov, which confirmed Pospelov, but
Well there are very serious doubts. I would be grateful for any advice )

Attributing Pohitonova.
 

And Eleanor V. Poston?
Forgot?

Help, - tell me how to call an expert Vladimir Petrov - phone and e-mail.
Thank you.

Pospelov - no expert.
He is soooo things signed, I'm sorry .

====
As for the signature.
Basically Pokhitonov was signed "Pokhitonov", or "ff", look it up yourself , not specifically check.

If he signed for once without the letter h after the letter k, it's probably over.

Signature Pohitonova
 

Just look at one of the signatures Pohitonova , happened without a signed letter h and at the end of the set w.

Neustoyalost transcriptions, you know ...

What simplicity! Touching :)
