It is a shot taken by British photojournalists back in 1944, during his visit to Drvar, where the 2nd Congress of the United Alliance of Anti-Fascist Youth of Yugoslavia took place.
These shots were taken just 11 days before the German landing on Drvar in the operation of the official name “Konjic’s Jump”, and it is also the first recording in the history that includes Marshal Josip Broz Tito.
Take a look at the video.
