Signature is similar.
A picture is not very visible in the photo.

The plot does not guessed it yet?

The plot - not quite clear. On the one hand - a pseudo -Russian palace interior , an angry mob at the door, the boy (again - in Russian dress ), frightened , embracing his mother, and blessing the boy one . Like, everything points to Petrusha , Natalia , and the rebel archers . On the other hand : the Queen - in the European dress, with her head uncovered (and this is - if deliberate historicism Novoskoltseva other pictures ) ... Of course, by different authors (from Shteybena - Dmitriev- up of Orenburg ), the plot was interpreted in different ways. But! The very picture - a curve , oblique , with impaired vision and proportions , in a word - no relevant representations about the level of training Novoskoltseva . It seems to me , and not Novoskoltsev , and not the original and a copy of the original unknown (well, not yet been set . Sang all day .)
The signature on the submitted photograph is incised on a dry layer of colorful , raising serious doubts about its authenticity. Something like this , in general.

Poozhe that izbrazhena Archer riot scene in 1682: Natalia Naryshkin, Prince Peter Aleseevich and vozmzhno, boyar Matveyev Artamon.

Asking $ 15,000
   
Not in terms of a definitive answer, but at least it worth to spend time negotiating expertise and Comrades
  
The plot is certainly not positive, but only as an investment.

And why buy?
To further advance or at home on the wall?

   
Look every day for such a picture is difficult, therefore, considered the option purchase as an investment, without a frame size of 87.5 x 115
