Dear amateurs. It is really dusty trail from the frame. I tried gently wash - out. We appreciate your attention to this.
The second picture really is no signature (or I can not find it ), but , you see, is executed masterfully. Can you tell me who like style of writing ? thanks in advance

Alas, do not agree ... Believe me , dear Igor1957: if the forum participants saw your picture on even a hint of " masterly performance ", you would know about it first. :)
The first picture I would advise to show the experts. With the sole purpose - to see how the signature is related to the colorful layer. A " Kapustin " - for examination.

I do not think it's out of the Russian school ...
