What is it? And could these sheets, or anyone interested?
 

Paper, old, very hrupkaya.Risunok done, I think, a stencil or a ruler, probably gouache or tempera.Listy located in a folder with a collector who had passed away, so do not know if anyone have kogo.Spasibo or illuminate when and who it could tip.

That depends on who drew. Kandinsky or Puni? Whose signature?
If Kandinsky - something I like, of little interest

And how can we understand who drew them, if they have absolutely nothing?

The latest "list" is very interesting as puzzle.

This is not the last sheet is part of the first three.

IMHO neither odin.ni other artists would not allow himself to paint through the stencil .:)
