Help identify the person in the portrait

In 1947, in Leningrad was the retrospective exhibition Bobrovsky. Does anyone know anything about the catalog? Although, almost certainly, this picture was not there.

James, as well as got this picture of the previous owners? You did not try to dig provenance? I think that you are in one or two steps away from the family image of the face. While hardly the picture is often passed from hand to hand.

Generally speaking, we should look in Lviv Stein family. In 1971, his son was alive and by that time many years he lived in Lviv, little time had passed, so it is likely that in Lviv is his family.
