Konchalovsky
 

I came across two-sided sketch signed by Konchalovsky, just intesno opinions of others. Thank you.

Funny, what else to say. : D

Yes. A humorous inscribed signature.

  Most of his sketches AUC signed initials.

It's true.

Another thing is that the actual sketches in his work almost there.

With regard to dating.

Study with a man in a shirt I would have dated the second half of 1950, as a woman - even before!

Guy remotely smacks of "krotolova.

Well, probably, and Gioconda remotely looks like a portrait of Ginevra dei Bench.

At about the same extent.

That naive man who put his signature "Konchalovsky" to this thing chetverokursnika Surikovsky Institute mid-1950's, also thought about that.

Only thing is the 50-ies (if not early 60's), and "Krotolov" if not mistaken, the end of 1930 (guglevat will not).
If you do not even mean.
