Tell me who the author
 

tell me who the author of the picture

charcoal, gouache

1921

signature looks like - YOU

A.M.Vasnetsov?
 

it can be Appolinary Vasnetsov?

it can be COOKING ...

I think that the inscription means you appeal to sitters (I give you your portrait ...)

but who gives - is unclear.
I do not exactly Vasnetsov

and it can be read as BAK (BAK)?
Well, let's say: Bakalovich Stepan Vladimirovich ...

Do not invent.
Read precisely "YOU."

take a closer look at the signature and understand that the letter "M" is not here.
This tail, which introduces you to zbluzhdenie - just a continuation pattern (continuation of "gear" strips dating back to the top).
The last letter, "a" or "n" or "n" ...

I "tails" do not enter into error.
That is what you call a tail spelled thin line parallel to, and read "M".

Take a closer look.

Let us then focus on the compromise, let there be no " YOU " and not " WAC ", but - " Vale "? <! - ~ 1 ~ ->
