Because we like to guess the riddle (close to the transfer of "What where when").

There is a work of (oil on cardboard, good size, about 60x50), is a legend: written by some of the emigrants, brought back to Russia, the bottom piece of cardboard, which could be a signature and the year, roughly cut to insert some frame (!!!).

Go tell that to the picture have no relation, as well as material interests, just seemed very curious.
Any assumptions, guesses, recognition, if any, will not cause negative (I promise)
