Three different rubber censorship cachets were used in Mostar. One was "★VOJNA / CENZURA" (= "★MILITARY / CENSORSHIP"), the other "ЦЕНЗЫРИСАНО!" (= "CENSORED!") and the third "CENZURA" (= "CENSORSHIP").
The last one is interesting because it contains mirrored letter Z. It is unknown whether this was an error in the preparation of the rubber cachet or whether the cachet was of Italian origin where the mirrored Z represents S as CENSURA in Italian means CENSORSHIP.
Forerunner of the 1945 Mostar provisional issue, letter sent from Mostar (15.III.45) to Dubrovnik, free of charge as the sender was a military person, censored in Mostar with "CENZURA" cachet.
