Kropiwnicki?
 

I would like to hear the arguments, whether it be the work of Leo Kropivnitskogo?

Communal houses, 1967-68 (?), Oil on cardboard, 35h26 cm
The inscription on the back probably is not the author's

The current owner of the work really does not know anything about her background, but said that it was someone from the Moscow nonknformistov seems Kropiwnicki

At the time of writing, I would not doubt, but something like it has, in the same style?

I Kropivnitskogo not so well know, something to say

fabosch, hardly a style not his own, though smiley would have been to beautiful - it could be a "grandfather"
