What will Santa Claus
 

Is it possible for the remaining part of the master stamp set?
Thank you in advance.

Bad photo, but rather Ovchinnikov than Hlebnikov - but the price difference is still there.
<- ~ 10 ~ ->

The approximate cost?
Is it possible to establish the precise expertise author?

The slope of the letters troubling, I work at least that they have never met.

Examination can establish whether the object or product companies Khlebnikov Ovchinnikov and only.

Sad ..... I would like to receive items from the established name of the master .
   Maybe there are still individual characteristics and therefore differences in the technique of making any small parts , patterns , etc. or this is not enough for an unambiguous conclusion?
  It remains only to find an identical mark. Yet to find ....
  For Santa Claus question of price is still open.

There are, of course , but no one you exactly the photos , and even that is used . so , do not make a " clear conclusion " , I think.

   
I mean expert.

The examiner should keep the thing in his hands physically, so to speak, and to do that , I suspect , in this case, you need to buy this thing .
And then start struggles between common mind and a desire to make a difference in prices : and the like, and prickly , and my mother will not allow it ( c). :)

Yes, you're right, Cyril, struggles burst, torment and torture, in which the moments even incinerate.
In the presence of an object in the hands of an unambiguous verdict possible?

Yes, any expert will tell you that the DPI is.
