Somov?

[Retrograd]

On the basis of Ukrainian folk wisdom "Gurt i dad which served biti! , Decided to go to the distinguished body and its inhabitants for help.
    This portrait, I found long ago in the old folio, which once bought. The drawing was very complicated and repeatedly tortured. Portrait of himself to me very much, its pronounced "Secession". Attempts to make out the inscription on the reverse side failed. Search monogramista AS too. Then even the Internet was not.
   But recently stumbled on the same forum at a portrait Somov, suddenly remembered a picture.
The question of the next character - is he or I "drove"?
I quote also the image pencil inscription on the reverse side.
   I do not think that the work in connection with the state can count on some comprehensible valuation, but with a cognitive point of view of another portrait Somov - a small opening.
  I hope for your favor and interest in the subject. Thanks in advance.
