Signature I do not know, I can not read, please help. Unfortunately, the previous owner overdone - after a wash now, I decided it provoskovat, which spread the wax with turpentine and a liquid solution provoskoval so that the solution is passed through the ground and on the reverse side of the picture, hence the spot. Photographed in the shade and the sun. Thanks in advance for help.

It is difficult to say.
In style similar to V. Tokarev, but the signature is not so.
It is possible that a Ukrainian?

Typical 60's, in my opinion.

Guys, new ideas did not appear?
