Sewing course in Prievidza

This photo shows a sewing course in Prievidza during the 1930s. Fourth from the left is Katarina Kohnova, the daughter of Kohn, the owner of Patria printing house, known all over the country, as towards the end of the First Czechoslovak Republic it printed Vcelar [Beekeper] magazine. I don't remember the names of the other women anymore. The man on the left is likely Mr. Polerecky, a Singer Company representative. The photograph was taken by Adolf Kramer or Dezider Braun.
