Help identify the author natyurmotra

[Parmenio]

Dear experts
I have here a natyurmotr, which I like.
However, the artist who created it, it seems not at all worried about having his name on the painting descendants could read. On the one hand, I just want to know that I have, on the other hand, this passionate bouquet at my unenlightened opinion deserves to identify its author.
Maybe someone familiar with that signature? She painted with a brush so thick that I was even the first letter I can not define! I see only the "Y" in the end. Maybe you know this style? This hand?
The picture is not old - with my t.z somewhere in 50's and 60's.
Maybe by a woman? Because the thing is very stormy and emotional. It seems that the author wrote it in one breath, in one emotional outburst ... By the way - basically it was not written with a brush - not znayukaknazyvaetsyaeta stick used by painters for the thick paint. Emerge from the head a spatula ...
Colors in the photo course garbled - in real life they are warmer and more saturated.
In short, I shall be very grateful if I could find the name of PC.
Although would help determine the direction in which you want to dig ...
