Bird Etching, Eastern European

Another piece that is bugging me for a while.
The title is "ptica", that means bird in few Eastern European languages. Most likely some of the former Yugoslavian republics.
"Ribi.... S." or whatever it says is either the name of the artist or the location the art was made. And then you have E.A.( artist proof I believe) followed by something I cannot make at all. Maybe that is the artist's name?
Any suggestions will be welcomed.

 

Ale..shenko?

 

The word Ptica is Bird (it's similar to the Russian word for bird, птица, but not in Cyrillic).

According to Google translate, the Serbian version would also be in Cyrillic... and would be птица. The translator is bringing up Bosnian as the language that would use ptica. However, I see that it might also be Croatian...

Sorry, I see that you already knew that ptica means bird.
