Perhaps Rostislav Lukin
 

Excuse me for troubling you.
It seems that this is not Lukin, despite the fact that the picture from a good family, and the seller quite confidently asserted that it Lukin, from a private collection :)

Have a look please.

Thank you.

Lukin, Rostislav Vladimirovich

1904-1988 Belgium

Now revised the book Jean-Claude Czmara of R. Lukin.
Neither the manner nor in a signature - does not like.
