"Portrait of a man" about the late 50's..
 

obviously, Ostrovsky..
the signature begins as Cousteau... and then it is difficult to disassemble.
I would like to know Your opinions on account of authorship and the expected pattern.

Bic may be Kustova Irina Petrovna / 03.01.1932 ?

[QUOTE=Bic;3320581]obviously, Ostrovskogo@

Bic, pay attention to the obvious absurdity. The model is depicted sitting with a book in his hands. However, Ostrovsky, as it is known, with 24 years of age was bedridden incurable disease - in fact, after this he has seriously interested in literature and began to compose himself. For famous pictures of the 1930-ies Ostrovsky posed lying down. So either Your picture is not Ostrovsky, or the author did not bother to delve into the basics of the biography of the model, and therefore did not give his work a special value.
