Oriental girl with tambourine - who's the author?

[Asty]

Please help me with the authorship of the picture - maybe someone knows an arm or a signature? No frame , a canvas on an old form , not in very good condition , just lying under the bed. The artist's signature is visible clearly , see the third photo - LP , TV , or PV, is not to disassemble .
If the quality of the first two pictures is poor, try to do better .
