My father Zoltan Biro with graduates from the Mostar gymnasium. Zoltan is the first boy on the left sitting in the foreground. The other people are probably his friends from the same grade. The photo was taken near Mostar in 1930.
When my father finished primary school, his family moved from Subotica to Mostar. My father completed high school in Mostar and then enrolled in law school at the University of Zagreb.
