It turns out they studied together in the Vitebsk Art School (School) 1938 /1941.

If school funds are preserved, most likely they will be in the Belarusian State Archive-Museum of Literature and Art: http://archives.gov.by/index.php?id=922684

Or the State Archives of Vitebsk Region: http://archives.gov.by/index.php?id=636517
