Here's a picture (photo 1 and 2) :
The paper /pencil . 18 x 11.5 cm
On the back (bottom ) the signature in pencil:
I read as
P. Charibine (?)
Could this be the
Paul Anisimovich Kharybin ( 1890 - after 1930 )?

In 1918 , if I remember correctly, he went to France , died in Marseilles (?)
If you have more information about it , share, please . Published several letters to his PD Ettinger , but light on his biography, it does not shed . Thank you!
In the web found a couple of his drawings (one , by the way , the signature is
Charibine, and not
Kharybin, as specified in the database AI) : Photo 3 , 4
